<human>: My ex (23m) stopped speaking to me (21f) a few months ago because he deserved someone prettier. Fair enough, I got over it. Or, at least I thought I was. He contacted me a few days ago (after having blocked me for so long) and asked me how I was doing, etc. Then, we quickly got into an old habit. Sexting. We did that and he says how he misses the bdsm relationship we had, and I did, too. But I really just missed him a lot. Not the sexting. Him.

He texted me tonight saying how he couldn't stop thinking about fucking one of his friends girlfriends and it just made me feel very weird. I felt jealous or disgusted or, I'm really not sure. I just feel really sad talking to him, but I missed him and I guess I'd rather be sad and talking to him, rather than not. I'm aware of the toxicity of this relationship, but I can't stay away. Has anyone else ever been in a similar situation?

Can you condense the text into a few key points?
<bot>: Ex blocks me because he says he deserves someone better looking. Contacts me 8/9 months later for BDSM sexting relationship.
