Did I miss the one? Late night thoughts.

So I've been occasionally hooking up with this this guy now for a few months and recently had to go out of town for work. We texted and talked while I was gone and recently when I returned I caught his profile on Grindr.Don't know how to exactly feel about this. I guess I feel a bit of jealousy, betrayal, but at the same time relief.To elaborate we were not in a relationship but treated it almost as such. We talked when he got out of work, texted all day, hung out most nights and went on dates. He told me that he loved me a few times and wanted me to meet his parents, also when I would bring up other guys he would get jealous!I feel jealous in the sense that I feel slightly inadequate that he would go looking for someone, betrayed because we were getting close, and relieved because I know he deserves more than what I can offer.I thought about it for awhile and I still haven't developed romantic feelings for him. After my previous relationship every other guy hasn't attracted me romantically. Even things like making out, cuddling, and dates are a turn off. I've been trying to connect with guys but it doesn't happen for me anymore. It's like after falling in love with the man I was willing to give my life to I can't connect with anyone else.Well this guy is a great catch, and everything I would want in a man but I don't love him. I feel when he pushes for us to do things romantic I go through the motions and I feel disconnected. It's not fair to him, he deserves better and I think I should let him go. I know I would be happy with him but I can't change my feelings. Any advice would be appreciated, Thanks.
