Pregnant with baby number 5 and suddenly single

Two weeks ago my partner of 7 years flipped out over something minor and I had to ask him to go stay at his mums because his behaviour was upsetting the kids we already have.

I expected him to see what he did and want to correct his behaviour. I expected him to care about his family, the fact that I'm pregnant and his recent promise to stand by me, that we were a team nomatter what because we didn't expect this baby and I didn't want to end up a single mum to 5 and struggling without financial help or even emotional support.

The last two weeks he has acted as though he is on holidays.

His mum cooks for him, does his washing etc and he doesnt pay to stay there so as you can imagine he sees that place as better than here although I do all that he pays towards bills so his finances are improving over there and he isn't contributing here at all.

He also hasn't made any effort to talk to me, spend time with me or show me any love. He's seen the kids a few times for short periods but then uses that as a reason not to contact me again for days.

He's not being a dad. Or a partner anymore. I'm feeling so let down that he doesn't love us enough to try to fix things by fixing his behaviour .. with actual an anger management course or talking to a counsellor truthfully. I feel so hurt that this pregnancy has been sad when he knows how important I feel it is to be happy especially this time round. I'm lost. Very depressed and not sure what to do honestly
