Bar scene dating is much different than real world applications. I for one find it's usually a bad thing to talk about the ex's, even if it was a good experience. I was never good at the bar scene. If you go into a bar find the furthest darkest corner you can(ever bar has one) and that guy you see sitting there all alone drinking and just "watching", yeah that was me years ago. Now i stay away from bars altogether.
Not like it really matters but I don't have much experience with ex's. I'm 32 and I have dated a whopping 5 women. Of those 5 3 sucked for various reasons. I've only ever told 2 that I loved them. I was engaged to both of those. One of them ended because, well I still don't know the reason. She never told me. The other well, we go into that, not unless I'm so drunk I won't remember.
