Met a new guy

[AlphaO]

Some advice please :
I met a new guy and he happens to be really good friends with my roomies boyfriend. I have been on the single train for a while now after getting out of a serious relationship, and occasionally have hooked up with my ex.

Well, I really want to try and date this guy, but my roomate is a little weary cause she knows that I have gonea little crazy while in my single days (mind you I haven't been single for about 5 years) He is a super nice guy and I would never intentionally hurt anyone! She says that guys just fall for me (which is not true) and that I tend to break their hearts (again, disagree).

I guess my question is, how do I prove to her that I am ready to date people, more specifically him?
