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

25 male btw. So I've been cheated on in pretty much every relationship I've had. Mostly because what I do precludes me from being either emotionally available or in the more recent cases actually able to be there. I've also been the guy on the side a lot some unknowingly, other times I just didn't care. Basically this has led me to feel like there isn't any point in taking any relationship seriously, which has made me an asshole. I don't want to be an asshole. 

I've clearly put women who I respect and like into an FWB position and hurt when they realized it wasn't going to go anywhere. I've been up front about it but feelings are feelings. Its not that I don't want to to be in a loving relationship, I just feel in my gut like everyone is a cheating [redacted].  So basically how do I stop having that feeling? Or maybe I'm just attracted to that type of woman so how do I stop doing that?
<bot>: I think everyone is a cheating [redacted] and am questioning the validity of my thought process so I don't die alone.
