I just don’t know what to do anymore

So I just lost my mom 😭 two weeks ago and my husband hasn’t been supportive what so ever. He has been giving me the cold shoulder and there are times he will snap at me. I finally send him a message explaining how I feel and I told him I think we should separate and he responded by saying that he is truly sorry on how he has been acting and that it is his fault and he said he feels real bad but he thinks it’s for the best especially that we been arguing a lot 😕. I know we argue a lot but what does that have to do with the way he has been treating me like snapping at me or ignoring m while I’m grieving. Like I would try to to talk to him and he will just get up and leave to the other room. I know I should tell myself forget him because I don’t deserve this but I feel like since I’m grieving right now, I’m so desperate to feel some love and caring from him if that makes sense 😞. I just can’t believe I just lost my mom and now I get this from him. I just don’t know what to do anymore because I have so many mixed feelings right now that I just don’t know what to do.
