I could really do with some advice / comfort
My husband left me 3weeks ago I'm dew to have his baby next week.
I have known my hubby for 8years we have been together for 6years, living together for 5years and married for 2 & half years. We had a two year engagement because we didn't want to rush in to things and have always done things at a pace we were both happy with.
We are both 30, I have a 12year old son from a previous relationships which me and hubby have been raising together since he moved in with us.
I had been broody for years but waited patiently for hubby to be ready for the next step, when he said he was ready to try for a baby he was so sure he swapped my birth control for folic acid.
So 3weeks ago I was awoken by my gorgeous hubby we made love/had sex he went to work and I got on with what was normal. cleaning the shed, ordered his birthday gift, walked dogs and started to sort out lunch for when he came in on his lunch break as he did every day.
He sat with his lunch looking pretty un happy so I asked him what was wrong, he said I'm not going to like it! So instantly my pregnancy brain is saying the worsted it could be is he doesn't fancy me while I'm the size of a hippo.
when he eventually comes out with it he says I don't want to be with you any more and that he needs space.
It felt like I had been hit by a bus, I never saw it coming...!
I know he hasn't been the happiest for a couple of weeks, but i had put it down to I had gone in to early Labour at 33weeks which freaked us both out, me being put on house rest until I made it to 36weeks, his work hours, and the usual pre baby worries money, small home, first time dad stuff.
Not I don't want you any more...
I said if you need space your parents are on holiday for a couple more days so you can go have a bit of time to think at theirs. Which he did I truly believe he would make it more than two day with out wanting to be back.
So after 3nights away his parents came home he told them he had left me then came to tell me his plans. "I'm going to stay with a friend until I get a place to stay, You will have to claim benefits, I'm taking the car and their is nothing I can do to save our marriage except give him a lot of space I need to do this".
He now has a temporary flat, and spends all his spare time with new friends he hasn't even known a month, which includes spending a lot of time with an 18year old girl who is calling him her best friend, going to the cinema, bars and generally acting as if he's single and 18 or 19. He isn't wearing his wedding ring which he asks me to keep safe in case he looses it, when I asked him if I could have our marriage certificate he decided to keep it and has it locked in his gun cabinet.
He isn't acting like him self completely pretending to be some one else to the point he went horse riding at the weekend, when he hates horses. He spends almost no time with his real life long friends and hasn't even told some of them.
I just don't know what has gone soooo wrong?
We have spoken since he left which hasn't really given me any real incite, he says he can't bare to live with me anymore, any other things he gives as reasons just seem like silly excuses none of which would be reason enough to quit your marriage and family.
I have got him to agree to meet up tomorrow lunch time, so I can try to arrange how he will help during Labour?
God knows how to deal with out relationships or lack thereof.

Any ideas.....? So confused, hurt, sad and angry
