Worst Roller Coaster Ride Ever

Hi All,
My bf of 14yrs (lived together 11 as of today, actually), broke up with me about 5 weeks ago. His reasoning was that he hasn’t been happy in the relationship for the past couple of years. I did a couple things that really hurt him, and he just never got over them. I never cheated or anything, but did betray his emotions. He isn’t one to forgive and said that he would never get over things and is tired of pretending to be happy. He mentions that he feels trapped all the time too.
Since then, he hangs out a lot with a female friend, but I know it is strictly platonic. She was going through a breakup as well, and they bonded through commisery.
Backtrack a bit, we co-own a house. Over the years, our belongings have merged together, we did EVERYtHING together, even grocery shopping. The two of us aren’t social people at all, so there is still a great comfort in not doing things alone.
So after about 3 weeks, we started hanging out a bit (we live together, making NC very difficult). We went to see the super moon at an old hang out, and he held me and told me how beautiful I was. We chatted for hours that night. Over the course of the next week, he started sleeping in bed with me off and on. We cuddled. When he’d get home from work, he’d kiss me on the cheek or forehead. He even bought a locket and put my picture in it. He wears it time to time.
Being that we were bed sharing, one thing led to the next and we had sex many times over the course of about a week. After the first time, we chatted afterwards and he brought up the “IF” word, and that it would ale a long time, if things were to ever work out. I was elated. There was a two day period where something was up and he said he was starting to feel the old negative emotions again, but still, unsolicited, slept in bed and cuddled a lot. After we had sex a couple of times, he said, out of the blue one night as we were laying in bed (didn’t do anything together that day) that he hopes I’m not getting the wrong impression and that things are not going to work.
The day before yesterday, we took a trip to the beach and had a great time. We held hands while walking around and overall had fun.
Yesterday started amazingly, but turned bad quick.
He mentioned that his next day off, he and his female friend were going to hike. They hang out a few times a week, and I don’t make a big deal out of it, usually. This time though was different. I mentioned a long while back that I wanted to go to the springs and he did too. I had brought it up a couple times, but it had been a while and he forgot. I said I was really bummed out, and it did hurt a lot that we had planned something, but now he’s hiking with his friend. He was upset that I didn’t mention it before. Because I was feeling blue, I started pseudo joking about wanting something bad to happen to me, and he went off the deep end trying to push a date to sell the house and break away for good. We are back to where we began. Last night, I asked him why he didn’t want to sleep in bed anymore and his response was that he is depressed from it because it feels like we are dating and it just reminds him of how unhappy he was with me. Ouch. He was the cuddler half the time and slept much better than when he goes to his room.
So many mixed signals and I just don’t know how to take any of it.
I am working on myself. I have schedule therapy, bought new clothes, got a haircut, work out more, and will be taking up a hobby that will basically be a part time job itself. I also am going away on a road trip for a few weeks in Oct/Nov.
Any thoughts? The sex, bed sharing, cuddling and all may have been sparked by my suggestions or flirtation, but I never asked for any of it. This is becoming too much of a roller coaster :'(
