Don't agree with your assessment at all. I'm not saying avni is right in everything she's done but neither has Neil. Her motivation fir every broken promise was fairly legit from her perspective and when it wasn't it was not really avni but a character destruction by CVs. But let's ignore that and take it at face value.
She went to RM because she wanted to get Neil out of his guilt. She knew he would not take a slightly offbeat or different route because he was hell bent on going by the book but time was ticking and he was dying of guilt. And she could not see Neil like that. And she did make good plans there. Just that some of them backfired mainly because she trusted Aman. If it wasn't fir Aman Neil would have got the message to postpone his raid and not got suspended or atleast she would have come out of the basement and alerted him if Aman had not drugged her
She never left Neil. When he disclosed the past the first thing he gave her was an out. It was when she said she'd not let go and stick by him that Neil really felt overwhelmed and accepted her proposal and confessed. The only time she offered to walk away was when she had been completely cornered and was weak in the moment. She did not just leave after writing a letter which is the route that a k serial bahu would have taken. She discussed it with him and when she saw his POV she dropped the plan
It was not her who suggested getting married to chuhi.it was bebe and later it was Neil who decided to go ahead with the drama to get a confession and avni very cutely said that don't get married for real
She stood by Neil as much as he stood by her. When she "betrayed"him and married him by "dhoka" she was forced by neela and she was mad with revenge and Aman had to be saved. Rhea had fled, dvm was going to lootofy khannad. From all angles she felt like it was a calculated risk and she intended to anull the marriage asap. Neil himself was going to fake the narriage anyway. So if they hadn't fallen for each other and Neil had also asked her to leave she would have gone. All she said those days was ehsaan and Neil rebuked her for it saying he did it because he wanted to. So she stuck around because she got signals from Neel too that he was interested.
Until Neil avni was masked by ananya. She did not speak her heart, she was always on guard she had never had a family . She had been betrayed by family. She had served tine in prison and her adoptive mom only encouraged her to get revenge. Only thing is she suddenly woke up and realized that in all that rage avni might murder the woman who killed both her parents, snatched her childhood, her identity and family. So Neil saved her from that.
After Neil she slowly learned to open up, trust. She put him on a pedestal. Fir the first time she felt belonging and family. So when she felt like Neil was ok with their relationship since he was not asking her to leave she found a place in everyone's heart including shweta. But obviously in one year she can't let go years of baggage so she still heart of heart was a little insecure. She felt bad when she thought Neil was apologizing because chuhi asked, she was furious when she saw chuhis reality. Only thing is she knew her husband usually demanded proof for everything and he would feel betrayed by chuhis lie becauae he did love her once upon a time so shee didn't tell him immediately. Anyway he found out. Then it was Neil who made the insane plan. Avni given past experience only had a smart backup which she wouldn't have gone through with of things had worked out. But next thing she knows she's seeing mishti being kidnapped again and vidyut has orchestrated the whole thing. This whole sequence was the most ILLOGICAL of all the illogical things CVs did but if we just go with it, avni had a gun throat in her hand by ballu. Chuhi was threatening to jump with mishti. What was she supposed to do. She would have never fired because she knew mishti was in chuhis arms. Neil had seen enough other evidence pointing to vidyuts role. But let's say vidyut destroyed proof. Even if Neel was forced to arrest her he could have reassured her that he believed her, but he was under pressure. avni would have gone to jail for him if he put in her that spot. Avnii wanted to run because she didn't want to be in jail for something she didn't do and because she didn't want Neel to be in a difficult position to arrest herr. If Neel felt like her running away would be problematic he should have confronted her and stopped it. He can read avni well. He knew what she'd do.
While avni was a broken soul with a bad past who had trust issues since childhood Neil was a normal boy who made an error of judgement when he believed everything his ex gf said. When he saw the trurth, instead of safeguarding his wife and t he childhe picked some insane route to tackle the situation which got avni in a fix. Now instead of explaining his position he has her believe that he does not trust her and imprisons her to"protectt"her, askss neela not to reveal the truth.
The maN who harped about communicating did not communicate his feelings to his wife who he knows is innocent!
Thennn for 6 months he did not find any evidence so now he's doing exactly what avni did in her childhood when the system failed her...go the vigilante route. And he's hoping that vidyut will get irked by this and confess! Whaate wow.
So if we just ignore all the loopholes and CV related character destruction and take the story at face value I definitely feel like between Neil and avni, Neil's mistakes have been costlier and more damaging to Avneil than avnis. Avni doesn't need anyone to avenge her. She'll do it herself because she's not gonna just sit and watch some guy destroy her life and get away with it. She will make sure she avenges it. And I dunno if she plans to kill him but if she does and then she gets arrested she will happily go to jail now and serve her time for a crime she did commit.
So I'm sorry I am provoked to rant when you say does avni "deserve" Neil?! That's unfair
You are entitled to you POV of course but I'm not ashamed to admit that as much as I love Avneil and both of them individually if I was forced to pick a side, I'd pick AVNI always!
