<human>: Give me the gist of the text in a nutshell

I've had a few girlfriends and plenty of female friends, but I just seem really confused by some things:

1) My regular friends have told me I could do **much** better than all the girls I have dated, yet all the "better" girls take little to no interest in me in that aspect.

2) It seems girls I am most interested in (fit what I'm looking for best), are driven away from me the most, whereas those I don't consider compatible are seemingly very attracted to me.

3) I'm not in the best shape, getting a bit of a gut, but not bad. I also had a really good body last year, but also got me nowhere, which caused me to result to where I am now.

4) I've tried being the nice guy, the cocky douche, the coconut guy, and mixtures of all. Not changing my personality but more of my impression(?).

I just get the feeling girls feel creeped out by me when they are with me, especially if it's just us. Maybe I'm being paranoid or whatever, but it's just a growing concern that I would like a bit of help with. Any advice is greatly appreciated. Maybe I come on too strong but I dunno. If I am not clear enough, I can clarify some more.

Please don't sugarcoat it. I can handle bluntness and it will help me best realize what to do. Thank you in advance for help.
<bot>: Unsure of what I do wrong that makes me feel like I'm off-putting to girls I am attracted to, looking for some advice/criticism.
