Yes. Really. She didnt get with anyone before divorcing in the movie - if you’re talking about the kiss, that was wrong but it wasnt “getting” with someone. People make mistakes - people are young, selfish and sometimes not thinking with a clear head and fall into pressure from parents.
If people can fall in love, people can also fall out of love, thats not selfish! feelings can change.
I dont know how you can be so judgmental and forget that humans are not God.
Maybe I feel this way because I’ve gone through a divorce because it wasnt the right person and we parted ways after being married for a very brief time. Either way, everyone is entitled to their opinion, I just know that it’s really easy to judge without being in that position.
