Is my boyfriend who he says he is?

Hello, I am just gonna get straight to it. I met my boyfriend a little over a year ago, he's really sweet and does a lot for me. But when I first met him his sister emailed me and told me to watch out, that he will chew me up and spit me out, and that he's cheated on every women hes ever dated. She painted him as a monster. I havent seen that side if him but i do know that hes had a real troubled past. I never told him what his sister said because i didn't want to hurt his feelings, but its always in the back of my mind. Should i tell him? Also He drank a lot when we first met but stopped, but now that he's working out of town he calls me and he's completely drunk, then when I see him he looks shot, wore out. He smokes like a chimney and coughs all of the time and I worry for his health. Part of me wants to leave because I deserve peace and I fear that his health is gonna fail. He's only 44 and is having problems already. There's so much more to this but I will post separate. Thanks everyone, I just don't know if I'm wasting my time and what I should do. Sucks cause we get along great.

That's a tough decision. If you're living a healthy lifestyle and he's not, then your reservations about the here and now make sense. I don't believe becoming a caregiver prematurely is how most perceive their future lives as partners. Are there other things(aside from the other post which I read before this one--which this makes those reservations a lot clearer ) that give you pause?

The call from the sister has got to be one of the more curious pieces of information that I've heard of a sister doing. Are they close? If not, keep in mind, there's his side, her side and the truth.

So you’re influenced by his sister’s words
