<human>: Can you provide a brief rundown of the text in within 3 sentences?

I've been involved with a guy for close to a year. He pursued me from day one, ending up one night making me a lovely dinner before we slept together. He put in a massive effort that night.

I tried to reciprocate by inviting him to dinner but he said he didn't want me to get "the wrong idea", and never came over due to work. He said that he would happily keep sleeping with me, but it would get messy. I told him that I can't sleep with someone without developing attachment. He went cold for another week, before asking me around multiple days in a row. He reinitiated that he doesn't want a relationship, only to sleep with me two nights later (initiated by him).

For close to 3 months now we've been consistently hanging out. I let him contact me for 80% of it, and it's not unusual for us to hang out 3-4 times a week. He gave me the keys to his place, and started frequenting mine. We would walk his dogs together, watch movies together, and he would tell me his secrets, and would we would make plans for the future. However, we didn't sleep together again. He got extremely protective of me when his mate came onto me, going as far to make sure I got home safely. I made it obvious that I liked him.

I honestly thought there was something there (close friend and he still liked me). Last week I told him that I like him. He again said he doesn't want a relationship because he had stuff going on (he does have stuff going on) to which I said I understand and I just wanted to be honest about how I feel.

That was over week ago and I haven't heard from him since. I've seen him three times since in group situations and it's not awkward.

I have no idea what happened, or what to do now, or even if there is anything (even friendship) is left. Redditors, what happened and what do I do now?
<bot>: Guy is into me, sends mixed signals. Goes AWOL when told that I like him. Not sure if even a friend anymore.
