I am I clueless or is he playing me to avoid hurting me?

Recently, I starting seeing this guy my friend hooked me up with whom I thought was sincere. He said to me that he was looking for a girl who was real. He had me convinced that he was into me but, after we had he began to call me less and less. So, one day we had a miss happ and there is a possibility that I may be pregnant. So, I approached him and he was mature about the situation but, he's still avoiding and his friend is returning his phone calls to me. The situation for me has made me so mad that I have blew up on the phone to this guy at least twice and his excuse the first time sounded sincere and that he was having problems wit his baby mom and was trying to avoid any seriousness wit me. Then we slept wit each other again and he still avoided me the friend still returning his call and now his baby mom I was told is trying to move in wit him because she is homeless. I still have not poss. preg test. but missed period. I call him over and over and he is avoiding me.Am I crazy
