For me it was a series of events that lasted about 7 years. I got out of the military and dated this girl for two years. After about a year she kept distancing herself and I let it drag out for 1 more year. We lived together but she chose that she wanted to do everything except be around me. She joined a total of three softball leagues and I would be lucky if I saw her for more than a couple hours twice a week. There is more to that relationship than just what I said but for the sake of trying to shorten this we broke up right around our two year anniversary.
After this I decided I wanted to be single for a while and just try to get my life together. Fast forward another two years and I met this girl at a house party. We hit it off immediately and it seemed too good to be true. Well about 4 weeks later she surprised me with "I'm moving to Vietnam next week to teach children English." Now I totally respect this and think it's awesome, but a little heads up would have been appreciated. Obviously this didnt last.
Fast forward two more months and I met this girl at college. Very laid back, wanted to chill, go to concerts, and just was a fun time. So again, about four weeks into this relationship I start getting violent calls from her crazy ex boyfriend and it was clear these two weren't over eachother. I noped out of that situation as fast as I could.
Now for the last one which was about 3 month after the crazy ex incident. This one was the worst for me....I'm the best man at my brothers wedding and I ended up meeting this girl. As corny as this sounds, it felt like love at first sit between us. I have never been around someone before that made me feel as good as she did. It was just her presence. Something about it always made me happy. After a few months of being together I felt on top of the world.....Then I get the "we need to talk" text and I knew at that moment something terrible was going to happen again. She came over, sat on the couch, looked me straight in the eyes and told me "I'm married". I was a mix of I want to scream at the world, at her, at everything....I just started to hate everything after that moment. Now it's been a few years and I'm way past all that but in the back of my mind I'm convinced someone will F me over again and convinced myself a relationship is not worth it. Sorry for the long story,
