depressed 32 weeks

hi to everyone, I am going trough a very difficult time. my husband's dad committed suicide 3 weeks ago and he found him hanged up in the office. since then he concentrated his energy in helping his mum and leaving me completely alone. he also slept at her place the first night and I feel so lonely I cannot explain. he leaves home early in the morning, around 7.30 am and comes back only around 8 pm, then we have dinner and that's the only time when I can talk to him. after dinner he lays on the sofa and fall asleep. I know it sound very egoistic but I miss him so much. we moved together in his town only 9 months ago and here I don't have any friends. I feel I'm not his priority, he never caress my big belly and is always very lazy when I ask him to prepare something for the baby. our relationship wasn't strong even before this tragic event but now I think he is not in love with me and I'm not sure I'm strong enough to deal with all this. don't know what to do...
