I want him back, he's keeping me waiting

My ex and I were in a long distance relationship for a year before calling it quits. Although it was a mutual decision I was the one who put the idea out there. I was just finishing my first year of University and was stressed out a lot during the year, he is a very happy and lively guy who tries to be optimistic all the time. We had both lost feelings because he felt that I was always negative and I felt he wasn't supportive. I was very cold after the breakup and pushed him away, which to him felt that I didn't care. I realized about a month after when I saw him that I still love him and wanted to get back together. He said he was going through a lot and wanted to focus on himself. Another month passed and he came down with some friends for the weekend, he took me out on the first day and it was amazing, the way he looked and touched was as if nothing has changed even though I was keeping my space. I wanted our time spent to be appropriate so I didn't go back to his hotel and denied when he invited me out that night. His weekend was very busy and we weren't able to see each other again. We both admitted to thinking the weekend would be different. Now, another month has passed and I still feel the same. We haven't gone longer than a week without some form of contact, we spoke the other night and he told me he still thinks we're eventually going to get back together, he also told me that he hasn't touched another woman and when I admitted to dating he told me to be careful with my decisions. I just slept with someone else for the first time and I'm afraid if I tell him he'll never take me back. He hasn't explained what he's thinking although he knows how I feel. I don't know if we're ever going to get back together and if I'm living off false hope.
