<human>: My ex and I had a highly sexual and intimate relationship for almost a year. Anyway, we broke up because he said he didn't see a long term thing between us anymore but he admitted it would be a rebound if he jumped into a new relationship quickly. Well, he did jump into a new relationship quickly...with a 32 year old woman no less.  However, he still comes to me to complain about her and talk to me sexually even though he is posting stuff with her all over social media, etc. Then, the other day he randomly suggested that I was going to "make him cheat on her" even though he claims he has never cheated before.

Why do this? Why even get into a relationship with someone else if you're just going to end up wanting to cheat with your ex? Is it because he likes her more emotionally but likes me more sexually? It makes no sense. He knows I was heartbroken by him and have a tough time resisting our sexual attraction. I loved him but I feel guilty that I am both turned off and aroused because I still want him.

Can you provide a brief overview of the text?
<bot>: Why would my ex cheat on his current girlfriend by suggesting we cheat together? Why even get with her at all in that case? I feel bad but am having a hard time resisting him.
