If pooja intended to divorce Adi, is she still wrong?

So in most cases of unhappy marriages - it's usually communication that's a problem - Also, at times it's not easy to keep asking your spouse to do something for you that doesn't come naturally to them - One could maybe ask them once, twice and they might even do it for you but it's no fun if one has to ask for things and get it all the time - So what if in this case you land up making a friend - and this friend happens to be of the opposite gender (talking with regard to straight couples here) and then over time you fall in love with that person because your interests are identical and that person understands you better - and you really don't want to change your husband to be that person because he's just the way he is - so you just decide to leave your husband and move on with this other guy.

Usually divorce happens in cases where the husband is abusive or evil and such but in cases where the two in a marriage are cordial friendly and what not ..but still are just not made for each other - what can one do then if in the course of making friends - one of those friends comes across as one you enjoy the company of more than your own spouse's? ..

I'm not trying to justify pooja ..but just saying ..perhaps she started off with yash as a friend and over time she figured that she and yash have so much in common compared to her and adi ..and while adi is her best friend he's not really cut out to be her husband ...so then she decides to tell him and wrote up her divorce ..but then the accident happened ...is she still at fault?? ..
