I just broke it off with my gf who I have been with for over a year and a half. ( dated another girl for approx. 6 mos before her) Im pretty sure that I did the right thing as the relationship was disintegrating before my eyes, but like any other time Im having second thoughts. The main reason, and a pretty important issue, is that her trust in me was not very strong and I spent more time unhappy then I did happy. What can I do to make sure that even though I am second guessing myself, I don't do anything stupid based on emotion?
