It sounds like your relationship is going downhill fast. Think of the situation from his side. He doesn't have to work yet he has his needs met. He also somehow is getting money if he is investing in motorcycles. He has no responsibillity and can stay out as late as he wants to hang out with is friends and partake in his hobby. When he is ready to call it a night he has a warm house and a warm woman to go to. He doesn't have to control his emotions because when he gets nasty nothing happens to him. He has no reason to change.

You are the only one that can change this situation. Stop making things so easy for him. Lots of people are depressed and do not act as he does. It is fine to help someone out when they are financially strapped but not working is his lifestyle. You are worth so much more. Find someone else who is willing to be a full partner and leave this bozo in the dust.
