<human>: My girlfriend is sweet, loving, and caring, and although I want to continue being with her, I've noticed that my own insecurities are hurting our relationship.

For example, if she wants to go out with friends, I get jealous, or sad, or angry when I know deep down she's just hanging with her homies. Sometimes I become afraid that she's cheating on me, when she has shown nothing but undying affection and dedication, even though we're long-distance. I've also started criticizing the way she does things and flooding my mind with relationship doubt.

I didn't know I had this demon in me as I was not like this at all when we were dating. I know it's me, and it's made me second-guess going into relationships. Even if I were to date someone else, I'd still have this problem.
