I've been orbiting this girl stupidly for the last few months, and I wasn't straight with my intentions from the beginning. I have really low self esteem so I don't believe that any girl would want to spend time with me, so when she did I caught oneitis really fast and I admit it was very counter productive and came from a scarcity mindset. Now she just fucked another dude, I am not mad about losing her as I didn't have her in the first place, I am just mad at myself and at my lack of success with women . Any help to get back up from here?
