<human>: Can you summarize the given text in a few sentences?

I have been friends with most of those guys for 5+ years some even 10. Here is the back story they've always picked on me for everything, the way I talked, did things, because I'm short. I always found it to be just because we were good buddies and really because they were all like that.

Fast forward to after high school graduation we kept in touch, and have been good friends, but the same pattern keeps on happening I always feel like the odd man out and they always talk shit about me because they know I am not the type to grow some balls. Couple months back I get this change of character (after a hard break up in which I suffered a lot through it) made some changes and started standing up for myself whenever I felt like I was being disrespected. I start seeing a change in attitude from then where they don't want to hang out with me as much and they always make me feel like that last fat guy to get picked when making teams. 

Examples:

*one of my friends asked us all to go eat, everyone else said they were busy and I said I was down, he didn't answer, then I asked if we were going and he replied with "my mom made food".

A coworker made a turkey bowl game and like a good friend I invited them to tag along they all came in and we made our team, just so that I could be scrutinized every time I didn't catch the ball and used in the most ridiculous positions when I'm not the strongest to play center.

*This week they cheated to kick me off playoffs and my friend being the commissioner of a fantasy football league said it was cool and defended them over me. 

I guess that was the last straw for me as ridiculous as it might sound. They are not bad people so I know that they are mostly acting like that with me by choice. Anyways I started seeing the pattern where I am the least desired friend. I decided to cut them off today and start making new friends after this. Am I wrong or what are your thoughts on it. Thanks in advance
<bot>: I noticed a pattern with my 10+ years friends that is making me feel like I need to cut ties with all of them.
