Need a male perspective

Hey there. I just want a man's opinion on my situation. I have a male friend who I have developed feelings for. We are close friends now for over a year, but his behaviour is rather confusing. We hooked up a couple of times and cuddled. But every time we get close and comfortable he pulls away. It happened a couple of times but he always came back. I felt like I was played like fool so I ignored him for a good couple of month. After some time him trying to contact me I gave in. Cause I misses him too. So I decided to give it a chance. But after we spend some time together and after we got close again I now didn't hear from him for a week. AGAIN! I'm so frustrated and upset with myself that I fall for him again. He gets upset when I confront him. He seems to have some problems with intimacy or don't know what. I'm sure he likes me a lot and I believe he really missed me, but it seems like he is just keeping me waiting. I know I can get over it but I'm still curious what might be the problem and not sure how to deal with it. I would appreciate it if someone helps who knows what to do or maybe even understands where he is coming from. Thanks a lot :)
