I am in a relationship with a 21 F for around 18 months. I love this girl, but I do realise it's oneitis also. The thing is, she does make me very happy but there are many things about her I do not like. The main one being she has been on the CC and has slept with other 11 people. I don't think I would like to commit to that, but feel if I break up with her I am going to be distraught.

I would just like some opinions please
