<human>: Can you condense the text into three sentences or less?

Background: since I was a little kid, I haven't been good with friends. In high school i didn't have any friends and I was the socially awkward loner. I hated being alone and I was rather depressed. I then started dating a girl for 2 years that kinda pushed her way into my life and forced me to be social, which i am super grateful for.
Fast forward to a year and a half ago, she cheated on me, we broke up and that was it, I wanted to be single when i went to university anyway. Problem is, when i went to my new school in a new city, all i wanted to do all first year (last year) was get back in a relationship. Time and time again, I got screwed over by girls and i just felt really alone. I have 3 of the best friends you could ask for but I constantly feel the need to have the attention of the opposite sex. Having my guy friends doesnt seem like enough.
In the last couple days, me and a girl who had been "seeing eachother" for 2 months now told me she didnt want a relationship anymore and now im lost at what to do. when we were together, I'd pick fights about the dumbest things cause i wanted her attention and for her to chase me and try to make me feel better. I did this constantly without even seeing it and thats why things ended.
For some reason, I miss her but I think its more i miss having someone in general. Ive heard the whole thing about girls craving guys attention if they had a rough homelife, it seems like im the same but with having a girls attention. Does anyone have any advice for me? I just want to feel content with being single, I dont want my happiness to be dependent on having a gf anymore. Ive thought about going to a therapist but I'm too afrid to ask my parents or seek it out by myself. Anyone have any advice cause I'm trying to improve myself for the better.
<bot>: Was a loner as a child, more social now but i feel I need a relationship and I'm always upset when im single because I want a girls attention, need advice
