i'll tell u why ichcha n veer are not made for each other....
ichcha is a mahaan person who dont sin....when she has decided that she has forgotten veer, she is 100% sure that she has indeed forgotten veer....she is ready to die for taps and as claimed by her in a very old episode ...is ready to sacrifice 100 veers for taps ("main tumhare liye sau veer kurbaan kar sakti hoon")....this shows that... for ichcha ..more than her ammu, thakur or even veer, tapasya is the one she loves the most...and so now and always she sees veer as taps hubby....and never as a lover...enter vansh who becomes the hubby of ichcha...and who keeps doubting her...she has no feelings for vansh as she had married him only for securing taps and veers marriage (she told this in the episode where she threatened to run ...and actually ran away from home.... claiming that she will marry only vansh)...but she is fullfilling duties of a sati savitri biwi n loving him for the sake of being his wife....and is trying to start loving him....in short...she had loved veer ...but now doesnt ...and will never dream of stealing her tappus hubby....even if they make up in the future episodes, she would be forever guilty...so it is a NO from her side (this is if she will continue with her current nature)...
now veer dont deserve a girl like ichcha who broke his heart and cheated him on his wedding day...(tapasya asked and ichcha gave straightaway without thinking of consequences)....as per his point of view...ichcha cud have avoided tapasya and his marriage....but she didnt and is firm on her decision that she will never ever like him again...to top it all....vansh, his bro is married to ichcha and is all crazy after her....if he dies and veer marries ichcha, again veer will feel that his sad troubled bro ke aathma ko kabhi shanti nahi milenge and will have vanshs sad stare in front of his eyes always...so it will be a definite NO from him...
(P.S. here his character is similar to ichcha...ichcha doing sacrifice for taps = veer doing sacrifice for vansh 😆)
If they were to make up they should have done it before vansh and ichcha got married, but now it is toooo late...
Just imagine Veer and Ichcha married...they were a good couple initially, but now they are more like a brother-sister duo with similar nature...i'm not trying to be offensive nor sarcastic...but i feel that however the CVs are twisting and turning characters (especially of vansh and tapasya)...it will never be the same as before for veer..ichcha...
...Tapasya was a jealous stubborn gal....now they are plotting the story in such a way that all bad things happening in the serial is coz of her...if u notice carefully they are making her interfere in many matters just for showing that what she wants is always wrong...and ichcha is always right...Vansh was a drug addict but now they are making him a psycho...most probably to kill him later....
