Heartbroken Over FWB – weirdest ending

I was friends with a coworker for roughly 3 years, married at the time. We would text/call occasionally, go to lunch, never flirted strictly friends. I had advised I was leaving my husband and in the middle of my divorce about a year ago he admitted to being attracted to me and we had a random hookup. We both enjoyed the sex so much it turned into a full year of having sex 2-3 times a month. He lives about an hour from me and I used to have sex and leave but it turned into spending the night, him making me coffee in the morning, watching movies, we even went out on a few occasions with his friends to parties.we would FaceTime for hours sometimes just talking about random things, not even sex. He said he values our friendship and opened up immensely while he is a very private person. He is 31 and has never had a girlfriend or has been in love. I realized about a a few months ago how deep I was in when he disappeared from texting for a few days. I told him it made me feel weird, he apologized but then it happened again. This time I told him I realized I have feelings because otherwise this shouldn’t be bothering me. He said that he has feelings for me more than just sexual but in the same breath that he doesn’t know if there is potential. We talked on the phone for a while ending it and I cried of course. He didn’t understand why we could not talk, text and be a part of each other’s lives. He said he understands the sex is done but doesn’t want me out of his life. After the call he text me apologizing. Said maybe this is what he needs to realize I’m the one, said he was even crying, and then started to talk about clothes and shoes he bought this week. Am I crazy or is that a strange way to end things?? Maybe he is just a really nice person but I can’t help but still think he will reach out going forward and I just need to move on correct? I’m hurting so badly but I anticipated him being on bored with a clean break and not questioning why we can’t still call and text.
