Hi everstorm. Welcome to Psych Central. I am sorry you are in a most difficult situation with your boyfriend. That sounds very stressful. Some couples try couples therapy to work out their differences and agree to disagree.

Grief is difficult in anyone but losing a dad for a man can be the most profound loss of his life. Some people break down and others postpone grieving, sometimes for years. It sounds like you have tried to be there for them. They may not want to let their grief out. Cannot force that just be there for them and maybe help if attending funeral.

Unfortunately some people have anger inside that comes out so stay safe if you find them being combative. It sounds like a difficult time for you and your boyfriend but hopefully they will keep their cool in these stressful times.
