Dont no what to do

Gaviscon

I just thought id come here for some insight. Im at a loss as to what to do im with my husband ten years married five with two kids and another due in a few weeks. Relationship hss been far forom perfect but since ive been pregnant with this baby has got gradually worse. I have never felt so alone with someone. My husband hasnt kissed or come near me since februsry aand when i approach the issue he shouts at me and walks out . He eventually comes bac tells me i have to change and that im not normal. I arranged last week a night for our anniverdary to see if i could try get him to talk. I had babysitter arranged and meal booked he came in and told me he was to tired and didnt go. A part of me knows that the marriage is over but im afraid of what hell do if i say the final words when i attempt to say it to him he witholds contact and money and sleeps rough and then blames it on me. There is no talking to him and i do feel guilty knowing he is sleeping in a car. If i tell him to come bac he comes bac but nothing gets resolved. I cant live with him anymore but i know he wont stay anywhrre else bar a car what do i do. Should i just leave him with the house that i no he cant afford on his own and walk away
