<human>: My first relationship of 1.5 years began at 16 with a wonderful girl and ended with her cheating on me. Right up until the last month, we had a perfect relationship. I can count on three fingers the number of major fights we had - no ideological conflicts, no trust issues (other than the cheating). Since then, I've had two short-lived relationships that both ended in infidelity and lying.

The first relationship's demise was mostly my fault. I was insecure and controlling, and demanded quite a lot of time with her. She lived 15 miles away, so I only saw her on weekends. In my mind, that justified my complaining when she said that she wanted to see her friends on the days that I felt should have been reserved for us. Several months after the breakup, I realized that I had these issues and began working on them. I feel that I have grown and matured in incredible ways, and have a much better hold on my insecurity, controlling nature, and clinginess.

However, I still run into liars and cheats every time I turn around. The only common denominator between all these relationships is me. Am I attracting untrustworthy girls? Is my behavior in all these relationships causing my partners to cheat?

I have found my attitude toward women and relationships in general to become worryingly cynical and bitter. I happened upon /r/theredpill the other day, and though I would never champion that philosophy, I found that a lot of the posts on there resonated with something deep inside of me. On the surface, I can recognize that there's a LOT of insecurity and psychological manipulation going on in that subreddit, but the general atmosphere of "all women cheat" is something that I find myself leaning toward more and more unconsciously.

The most pressing issue, though, would be my burgeoning trust issues. I find it difficult to imagine myself ever being in a long-term committed relationship, because the only types of relationships I know are ones that involved cheating. I'd like to change this attitude, but don't know where to start.

Summarize the given text in a few sentences.
<bot>: Got cheated on a lot, starting to have a voice in the back of my head that calls all women cheaters. I recognize this as irrational, but don't know how to make it shut up.
