Quoting KatyRP:" You shouldnt be feeling jealous just mad and upset that he dont put his daughter first."
people can't help how they feel...
OP... ((hugs)) I get it. my ex husband was an smurf.. never put any effort into the relationship. We had 4 kids together.. he never did anythign with them, never bought them anything, and was only awake for half an hour aday before going to work.
now.. he's engaged, takes the kids places etc.. they say eh's great now. They hardly remember when he was mean.. while that's great for them.. It bothers me. I'd have stayed if he'd put in HALF as much effort in our marriage as he does now. Last year for my kids birthdays they got NOTHING. Not even a box made cake (and yes he can cook) their birthdays are all in May. 2 weeks later he gave her an engagement ring. ugh.
