I have a good friend of over 3 years. He's always been a good friend but around November we started getting closer-I was casually dating a guy who was treating me badly and my friend was very supportive. I ended it with the guy and me and my friend got closer. I genuinely believed because of the way he was acting that he had feelings for me. One night we were drinking and he suggested we sleep together I thought this meant something but he said no he just wanted to be FWB. This isnt something I would normally do but I was vulnerable and desperate for some affection and trusted him.
Since then we've been meeting twice a week for 6 months, been on holiday, spent loads of time together. I have fallen in love with him. Then about 2 months ago we were talking and he mentioned how he had liked another friend of his (he only has women friends) this really hurt me but he said it was before me. I got really upset and said this hurts because I have feelings for you. He says he loves me and respects me but isn't in love with me and doesn't want a relationship. We have carried on sleeping together but things have changed. He talks about his other friend a lot, rarely initiates anything anymore and i'm questioning if i'm being used. He acts supportive some times but recently I have been depressed and he hasn't asked if I am ok. He isn't great with communication because he has autism and often misses out on social cues. I want to believe he genuinely does respect and love me because of our long friendship but everything seems to be on his terms and I've noticed he has this pattern of chasing women who are having relationship difficulties because he likes to feel like a hero. It's always about sex now-he's even bought all this kinky stuff to use and it's starting to feel seedy. He knows this is hurting me and yet still continues and I can't seem to find the strength to stop because I will lose my best friend and someone I love. However I am starting to resent him and this has really affected my mental health and I can't help but think even though he acts sincere he knows what he's doing but thinks its ok because he's been honest about not being in love with me.
It really hurting because I don't know what to do
