Such a different life than my boyfriend..

My boyfriend has this great family, parents have never split up and they are well off money-wise and get along great. He has never really had anything bad happen to him or gone through much struggle. While my life feels like it has always been a constant struggle, never met my dad, been homeless, mental illnesses that I have to fight off everyday, and lots of family problems. I feel bad for getting frustrated that he doesn't understand, because he tries to understand and that's all he can do.. I can't help but think sometimes are we just too different? I can't keep a secret of what my real life is like from his family forever and that scares me tbh
