I love him

I've been dating a man that I know for a while.. years actually, but only dating for a few months now and we're very different. I'm very close to his family and he has met a few of my family members.. but we are getting to know each other in a different light and we have been facing some difficulties... he has a lot of baggage and I don't. He has children and I don't. He lives in the fast lane and I don't. I'm very attracted to him and I care a great deal about him but I'm not sure if he's ready for a real relationship and I'm also not sure if I'm ready to take on this type of challenge. I don't know if he will make the sacrifice to be a better person for himself, children and the relationship we are attempting to build. It's scary because I find myself wanting to help steer his life in a better direction but I can't force someone to change. I find myself feeling happy and sad like an emotional roller coaster and it's frustrating. I guess I'm just venting here because it seems like a good place vent.
