I'll write about my cousin and his wife.
My cousins wife had the grass is greener crap. My cousin was getting jealous of her going out frequently with all these single party-girls, he would fight with her about it. He himself would just stay home and play videogames. His wife says its because he didnt want to go out, so she partied, and the fight over jealousy got her to leave. I dont think so, she had the grass is greener, plus active friends who partied. Actually, its both things when I think deeper into it. He was her first sexual partner. So, they broke up after an argument about her going out, she said, "you know what, its over... i dont want to be in a relationship anymore, goodbye."
Anyways, she went and slept with a few dudes. And she went as far as to promote clubs with her friends, so she was partying hard. She even slept with my cousins friend who he invited to his house once.
HE went out a bit, and got with his wife's ex-roommate and friend (oooo juicy!). And he stopped playing videogames. Note he did chase for a while, I dont know for how long, but eventually he gave up hope and stopped chasing her, probably around the time he met her roommate.
Like 7 or 8 months later christmas comes around. He sends her a text saying, "Merry Christmas". She texted him that shes feeling horrible and that hes the only one that reached out to her, that all the guys used her, and now during a holiday, she has no one. So, he takes her back and breaks up with the other girl (who he says to this day cant stop thinking about since she was sexually better).
Now they are married. Personally, I dont think this was a good story, no matter how she wants to spin things, she was pushed to settle because she was out "there" and realized guys do sleep with you and keep you as an object. That is her reality, the one she thinks is out there in only 8 months of searching. Its not that she couldnt find better, its just that she found waaaay worse.
They are happy together though. He doesnt play that much videogames, and she doesnt party. I do notice she has a significant edge in domination in the relationship, and I think its because my cousin knows she left, thats written in history, and he does realize she is capable of doing it again.
