Because I don't 
I do love him, we laugh together, he's a great father but all in all deep down I've always known he's not my soul mate. He's not very emotionally intelligent. He's doesn't get me really.
He has a great life, I do everything for him and the kids. I feel like he doesn't appreciate me at all. His lack of support became evident last night when I asked him to put our youngest (6m) to bed straight to bed after bath as I'm trying to instill a good night time routine (my DS is yet to sleep through I'm EBF so getting up in night is all me, I want his help trying to fix it) he said no he wanted to watch a film with DD and he couldn't do both.
There are two nights out of the week when he's not at the gym that he is supposed take over n I am go gym (or whatever). During the day on these nights he often rings and asks me to have them bathed, fed and ready for Film Night 
WTF do I get film night? I ended up staying at home and getting DS to bed myself (he slept through
) whilst he watched Disney.
There is a huge atmosphere, we rowed a lot last night in which he said some really hurtful things inc swearing, get out of his face, I'm tryin to stop him spending quality time with DD apparently etc. this was all done through text because we can't actually talk to eachother about anything deep or meaningful. he's not bothered saying goodbye or making me coffee this morning (he's always done this).
Right now I can't stand him and want him to go.
