does he want me back or does he just want a friends with benefits

My ex and I broke up 3 months ago. We were together for 5 years. Toward the end of our relationship it seemed as though the spark was gone. We were arguing…not seeing eye to eye. So he decided he needed out. So he left. I cried and begged for him to stay and work things out. But the more u begged the more he got cold toward me. So I finally left him alone. I told him I wished him well and to go be happy. So he left. He moved out. And it hurt so bad. But u can’t force someone to stay. So I just let him go. I didn’t call him or text him. He pretty much blocked me out of his life. So I went on with life. Kept my self busy. Got back into school. Started losing weight. And I got used to not hearing from him. It became routine. Well he called me out of no where and he asked if I was ok. That he had been thinking about me. That he missed me. And still loved me. He brought up fun memories we had and seemed so caring on the phone. Then I had to go so he text me. Apoligizing for everything that happened. We both talked about what went wrong. And how it was for the best at the time. He wanted to see me and made it seem like all he had was sex on his mind. I said no and he got mad. I felt bad because I wanted him to miss me…not the sex only. So I stood my ground. And he didn’t text me for a few days. He text me again yesturday and sounded like his old sweet self. We hung out. Talked cuddled. And he kept telling me how much he missed me and how I looked beautiful. It was perfect. We had sex. He held me after. Walked me out hugged me tight and kissed me. And I haven’t heard from him since. I feel he loves me but I don’t want to be a fwb. I don’t know how to feel now… 🙁
