I am embarrassed guys lol

So basically I was going to meet this guy who my sister knew as a child. I told her let me speak to him because he would be considered family to me as well. Mind you I think he had other intentions when he came to see me. When we met, we just spoke about our past and how our lives are going , . I noticed he was sending hearts and very talkative in text. I think he probably thought he was going to like me but it changed when he seen me in person. Which was pretty awkward he really didn’t talk much , my sister later said we would be cute together and I said no lol but he said I was not his type and he sees me as a sister which I believe he didn’t want to hurt my feelings .. boy did I want to put my head under a rock when my sister told me what he said..the whole thing was awkward. He was real sweet though but it kinda made me even more insecure . My sister says stay friends and see where it goes.. I told her heck no .. if he didn’t like me now what would make him change his mind later. I know my self worth and I don’t think any female should do That lol .. I’ll take the friendship which is what I wanted to do at first , I won’t ever consider going to a guy who says I’m not for him or got too much going on that’s fine
