Is it normal was it love or a crush

I am normally annoyed by people who are needy and clingy a lot. Even in relationships, don't get me wrong, I enjoy the snuggling and cuddling, holding hands and all that mushy stuff. But I do enjoy my time alone. So yes please, have fun going out with your friends when you feel like it, I will be fine. But there was this one woman who would cling on to me a lot. It was like I was the only person she knew. For some odd reason though I came to not mind her being clingy with me. In some ways I didn't want her to let me go. And if I made her upset it would bother me so much that I would try cheering her up, and apologize. When I was around her nothing was on my mind, she would ask me what I was thinking and I told her I don't know, it was like I was blocked out of my own mind not having a clue as to what I was thinking. It didn't work out though. She began thinking I was just keeping secrets and how I felt to myself. Which wasn't true. I Really could not think when I was around her. Like my mind was finally at peace enough to stop over thinking stuff or coming up with random thoughts. She knew me to be a thinker, to usually have something on my mind. I figure that is why she came to not believing me. So yeah, I don't know, it probably would of ended regardless because of her being so clingy, eventually it would probably get on my nerves enough to end it. IIN? Was it love? Or was it a crush? How was I ever ok with her being so clingy to me? When too much of that irritates me?
