We have been dating for 3 years, but we always ended up have sex in my house. He has all kinds of excuses to not go to his place... I use to believe him(call me stupid...). Untill now I still dont know where he lives. He never introduced me to any of his friends or families... His father died about 3 weeks ago, I said I would like to go to the funeral as his normal friend. He was totally freaked out. I dont know what i am doing now, just feel so sad. He did say he loves me and he is a sweet guy sometimes. I do feel he just uses me for sex. He always says he is difficult guy and he needs time. Is it true? Should I give him more time?
