Stuck in a one-sided relationship which does not seem to be like one-sided at times
I am like stuck in this confusion for long time now and still have not been able to find a solution.
I met this guy around 5 years back during my graduation, we started talking without a reason and became best of friends over years. He always used to act authoritative and protective against other guys, and always told me that I was very special for him. However, he also used to say that work was all he wanted to concentrate on instead of being in a relationship. Gradually I realized that I had developed feelings for him and told him like 6 months back. He denied me, and told me that career was all he would want to concentrate on in his life and he does not see a future with me. After this I started avoiding him so as to get over him, but he did not allow me do that. He wanted the same rights and special treatment as he had before. Many times would act ignorant, so busy with his work that he would have no time to talk to me but then would start taking extra care when he would see me go away. In fact after all this happened, he became really jealous about 1 of my friend, and started inquiring about him from the rest of my friends. He has supported me a lot but lacks commitment and tells me he does not feel for me. Now, I am stuck at a place where I do not know which way to go. This guy would say I am his special friend but will not commit, will not even let me go off.
I cannot interpret his behavior, because his words do not match his actions. I do not know whether I should stay with him the same way I used to, ignore all he has done and leave it to future to decide, or just stop talking to him. Please help me.
