I see a lot of people in this sub that say things like "you should be happy and confident with yourself, happiness should not come from someone else like a significant other", and I totally agree with this. I find that when I start liking a girl and we talk for a long time, I become more and more insecure, worrying about if she is talking to other dudes, getting jealous over small things, etc. I try my best to not display these insecurities, but I feel them. How do I get over this? At the end of the day, I realize that I can not control other people, and the only thing I can do is trust my girl. But I still worry about small dumb shit. I guess my question is, how do I stop doing this? What do I do to gain confidence with my self and improve my self esteem?
