Ah

I'm always being told that I'm too good for the person I like, but when it comes to it, things always go wrong. For example, I really liked the same person for a year. Stages passed when we would be very close, also when we would hate each other, and I got really hurt in the process. I finally moved on to someone who was very different. I'm not against smoking, but I don't do it myself and he smoked a lot. Things got complicated and he dropped me after a few months of getting somewhere. I've been told to leave things with them for a while, to see if someone new comes along. And they have, but I don't want to be hurt again, and he isn't very consistant. However, he is a very nice genuine person. Should I go for it or not?
