Can't understand ex Libra attitude, I need help!!!

I had been with an ex Libra for 8 months, and split up 4 months ago cos he couldn't handle the pressure when the relationship was getting more serious and exclusive, he felt losing his freedom and space so he called off saying he's not ready for proper relationship yet. We did NC rules for 2 months and we've started talking again but mostly he initiated the conversations. We get along quite well and I managed to control my feeling yet still able to be his good friend. He always cares and respects me, being understanding, helps me every time I need and talk to me constantly. But I know from the bottom of my heart I still grow expectation and hopes to be with him again and I was willing to give him space to sort his head out while being his friend so we can understand each other more and might be able to start a brand new relationship. Couple of weeks ago he suggested if we would go out for drinks sometimes soon? So I asked him if he wanted to go out on Friday but he was out with friends and didn't think its a good idea to meet up because he was drunk and said "we will soon", but when? So I was mad at him because I started to feel resentful and losing my patience to being just a friend and confessed I can't be friend with him anymore cos I still have a lot feelings toward him. He told me he's still attracted to me and fancy me so much but still scared of commitment (he hasn't dating anyone yet after me). He never wanted to string me along but don't want me to disappear in his life so he'd be happy if we can be friend and sorry if it wasn't what I want to hear. I called our friendship off and deleted all his contacts (BBM, facebook, mobile) because I can't deal with my emotion anymore, suffer pains under "friend term" and told him time for me to let him go completely. And yesterday out of blue he sent me a message saying why did I delete all of his contacts off? He thought I wanted to be friend? Why being friend with him would waste my time and hurt me? He misses me a lot and still want to be my friend? Please? I really don't understand what's this attitude? If he still fancy me a lot, get attracted to me, care about me and couldn't bear with the idea of losing me in his life then why don't he just chose to be with me and build up a new relationship? I would love to adapt, with being very understanding and supportive attitude to work out his issues with him but I don't know how to deal with him anymore. Please help me!! I really appreciate any advices :-)
