So my ex-girlfriend called a few nights ago. We dated pretty seriously for a year or so and broke up. Nothing too spectacular, we were just young and dumb (probably still are), but anyway, I accepted an offer to go "hang out" for the first time in about 10 months. We had a great time, drank a few beers, talked about BS for hours on end, kinda like the old times and stuff. You guys know the rest, da da da kiss.... ended up at my place with a bottle of red wine and a movie. Now left with the proposition of dating my ex girlfriend. Somebody talk me out of this...everyone else is supportive and stuff.... Am I insane?
