Ex boyfriend

Me and my ex boyfriend have been broken up for nearly a year and some change now. We had a messy break up but eventually got back on speaking terms after he emailed me telling me how he still loves me despite what we went through. We have messed around quite a few times, but nothing more than sex (on my part). Usually drunk calls from me, rarely from him. I am now overthinking because I can say I have moved on from our relationship, but I definitely still love him and miss certain parts of our relationship. He was my best friend before anything and I truly haven’t found that in anybody I’ve dated since him. It now has me in deep thought and I’m afraid I won’t find somebody who will treat me the way he did. He was patient and willing to compromise on basically anything I asked of him. We had our problems but I believed we would maybe be able to get back together in the future. The only problem is, I am no longer sexually attracted to him at all. I still love him dearly, but the physical attraction just isn’t there anymore. I guess that’s why I’m okay with us not being together, but I’m also wondering if I could be blocking a blessing? What does this mean? How could I have been ok with spending the rest of my life with him and only sleeping with him, and now I have no desire to have sex with him. It’s just not good anymore. Idk. I’m overthinking and idk what I’m actually even asking. Any thoughts?
