Relationship breakdown after miscarriage :(

[MummyC92]

I really need a bit of advice, I am feeling so low :(

Me and DP have already a 4 year old DS and recently decided to try again. We were lucky on first try and conceived but unfortunately at almost 5 weeks we lost the baby :(.
The day before I started bleeding DP stayed out for drinks with friends and ended up staying at his friends rather than getting the last train back, I was obviously furious as he didn't let me know and just walked In at 7.30am hungover, and we argued massively.

The day of the miscarriage he was supportive in his own way but the day after he said he was going to stay the night at his mums (5 mins down the road) to clear his head and deal with it all. He stayed there 3 nights and came back today.

I asked him to talk and he shut me down in flames, we argued again and I ended up in the heat of the argument telling him the stress he put me under the days before mc probably didn't help matters.

He threw his key at me and has just left.. I know that was an awful thing to say and now feel awful. I so want this to work but don't know how we will ever get through this :(. Don't know how it got so bad over just a few weeks.

The change towards me was very sudden, as weeks before he was excited to expand our family and had been talking about it for months before I felt ready to try, so unsure about his feelings now :(
I have apologised for what I said and I said it is just because I am emotionally drained and hurt right now that I've been left to do this alone.

I can't really do anymore until he acknowledges that he put himself first and abandoned us when we needed him, as he held it together the day it happened and I stayed in bed all day crying it out, I understood he might need a bit of time away to let it out and not be strong, I think a night would have been fair but the rest of the week took it too far.
