tldr: opportunity has presented itself to sleep with a guy (m26) who is in a monogamous relationship and i want to and i don’t feel bad about it. 

i (f20) recently had a friend tell me he wants to sleep with me if i’m down. likely because of my bpd, i really do not possess any cognitive empathy. i understand it in theory - but i just cannot actually apply it. i DO have very strong emotional empathy however. 

anyway, rumor has it he’s great in bed, i’m hypersexual, and i wanna sleep with him. 

however, i understand that helping someone cheat is not good (duh) i just don’t get how to make myself internalize that. i stalked his gf’s (f29) insta to try to humanize her more and try to get my brain to see that she’s a real person who my actions would be hurting, but, nothing. 

i don’t want to be a bad person, but i don’t FEEL bad/guilty/shameful about going through with this at all. 

any advice?
