<human>: Could you distill the essence of the text into 1-3 sentences?

As someone who was recently broken up with, and is trying really, really hard to move on from him...... Why do I feel so guilty at my burgeoning physical relationship with another man. I like this guy. He's sweet, he's smart.... But I don't want a romantic relationship. Which is a bit problematic, but I can work with that. He and I have talked about it, we're both adults. We know it'll probably end badly, but until that happens.... We're just kind of shooting in the dark. Neither of us know what to do. 

But, back to my point. In regards to my ex.... I'm not over it, obviously. Not emotionally, at least. But he was kind of just a big bag of dicks to me, to be completely honest. I love him. A lot. But, that doesn't change the fact that he broke my heart six ways till Sunday... He was everything to me, and it never mattered. So now that I'm trying to move past it, rebuild my self esteem a little bit, mend the broken heart, shit like that.... Why is it that every time I touch this other guy... Even if it is NOTHING sexual, I cannot understand why I feel so guilty.... I feel almost like I'm cheating on my ex... WHO I'M NOT EVEN TALKING TO ANYMORE. Its ridiculous..... Halp me, please. Halp....
<bot>: Trying to move on from prior painful relationship, can't do anything physical without feeling like a cheater even though I am 125% single and not talking to my ex.
