<human>: So this is my first time posting and I'm not even sure this is the right subreddit so if anyone would be oh so kind to tell me where it would be best to post I would appreciate it. (:

Anyways I'm 21 years old and I've never been in a serious relationship. Now I have had flings here and there but nothing serious because as soon as I feel it getting serious I start to panic and feel smothered and end up breaking up with them and mostly I'm already having my eye on someone else. I remember a couple years ago I heard somewhere that cheating was genetic and I don't know if it's true but I seriously think it is. My father cheated on my mother multiple times and even though I say it didn't affect me because I was too young to understand I am starting to think it did. I can't do relationships because as soon as we put a label on our thing I start to flirt with other guys and basically I act more single than when I am single. I would much rather be by myself and I hate having to answer to someone. I couldn't care less about what my partner does.
And another thing, I can't do PDA. When I see other couples doing it I just think how fake it is. I know they aren't going to be like that forever. I know that while the girl was hugging him he was checking out the chick that passed by.
And like I said I've had flings here and there but I've mostly been the other woman. When I see a guy that's in a relationship it's like I'm suddenly attracted to them and I won't stop till I make them stray. It's never gotten serious like leaving the wife for me but it's just mostly flirting and making sure they go home thinking about me. 

I can honestly say I don't want to be in a relationship anytime soon and everyone tells me 'when you meet the right guy' but I'm starting to think that I'll just end up fucking it up with every guy. I'm not sure if I have 'daddy issues' but I do want to know how to overcome my fear of commitment.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: May or may not have daddy issues and want to know how to get over fear of commitment and stop being attracted to older married men
