What To Do About Our Friendship?

I have been friends with a guy friend for about a year now as we met in grad school. We got closer as time went along and he event told me how he wanted me to be a part of his journey. It was so nice as we got closer and genuinely getting to know him. He has a really sweet spot nobody gets to see and I loved getting to see that. However, he did certain things that really hurt me. For example, I got him so many gifts (because I wanted to), helped him move to a new city, I even defended him when people talked crap, was there for him when he crashed out after finding out something about his ex, and I even was there for him when he was sick. With me instead while he did bring me gifts from another country (which was so sweet and I still have) it was clear I cared more. Even the parents repeatedly thanked me and acknowledge me for being a good friend. However, he was not a very good friend to me and hurt me multiple times and even left me in the cold one time and did not check to see if I got home safely.

Then a incident happened where I feel it really became bad after a mistake i made. Basically what happened was I was very sick prior to visiting him and his family. I nearly went to the hospital and was also trying to plan some stuff and I had bad brain fog from everything. I was to only be there about a week and 3 days I think. Then plans changed and I accidentally overstayed. He said some stuff behind my back to her and let me tell you…. the pain I felt in my heart can’t be described. I owned up openly and apologized to all of them as none fo this was intentional. Parents forgave me but he has been acting weird since. He no longer hugs me, calls me, text me, or anything and I feel ignored but apparently he asked of me as graduation. I miss our close friendship from the summer time and I am not sure what to do. I feel like I messed up but all my friends hate him and want me to forget about him. They said he was never my friend and it was one sided. What should I do?

Hi! I could not fit some other stuff due to space, but some things he did were. For example, he left me at a bus stop at 3 (degrees C) and couldn't call to make sure I got home safely. My feet were so cold that for months they were white, and I could not feel them until recently, around April. He wasn't there for me when my friend died, he was rude to me a couple of times, and I didn't feel comfortable calling him in certain situations. I also helped him with certain connections I had.
