To each their own I guess.. but I see flaws in this "wanting to get back together bit." If you had problems such as him dicking around with some other girl while you were dating.. then why go back through the pain and heart ache? I've been in ... sigh.. 5 relationships.. I have not screwed around when in them. So if you keep telling yourself "oh it's just how guys think" - well you are setting yourself up for a long road. There is temptation and there is acting on that temptation..
What happened with that girl is I became friends with her and he backed off. Plus we all worked together and I was made redundant, so I dont see how they are now. But she is happily in love with her guy and is moving to New Zealand in Feb next year. So even if we did get back together, I wouldnt have to worry about it as I dont work with them anymore.
And he stated time and time again, not just to me, but to other people that she was a friend and nothing more. He never found her attractive in the slightest.
