Is OTHER wrong in the post ? POST : This happened a long time ago (almost three years to be specific) but since back then I didn't know about reddit, and this thing still bugs me to this day, I must hear someone else's opinion on the matter.

So, there was this guy, let's call him Mike. We met in the 1st grade of primary school (I'm from Europe btw.) when we were just kids and basically we quickly became best friends. During this time we had ups and downs, but we remained best friends despite everything. Then middle school came. We went to different schools, but we still had great contact, also we established a great friendship with yet another guy, and so there was the three of us now. And finally highschool came. After three years apart from each other during middle school, Mike and I went to the same highschool once again, and even to the same class! But... This was the time things started to break.

With the beginning of high school, Mike started to spend less and less time with the remaining two of us. He began to hang out more with other guys, without us. Still, we had some kind of contact. In between the semesters I switched classes, and so we speaked to each other even less... But it wasn't the ultimate end of our relationship. You see... I had a crush on a girl from my middle school class, let's call her Monica. Monica friendzoned me for a long time, also after I told her that I loved her. And during the first grade of highschool (she went to the same highschool as us) I decided to break contact with her, as the relationship was clearly one-sided. During that time, Mike confessed to me that he'd like to ask Monica out (in a romantic way). I asked him not to, as I still was in love with her, I told him that when I stop having any emotions to her, I'll let him know and he can do as he pleases. He agreed. Long story short, Monica met with me after some time, as she developed feelings to me (that's a weird story, believe me), she also confessed that she met with Mike, despite my request. I was really mad at him, I felt betrayed. It was even worse because of the fact that he told her that they need to keep it in secret, so I wouldn't find out. When he texted me after some time, I cursed at him and told him to go to hell. He simply texted that he's sorry, and said nothing more. He wouldn't talk with me anytime later. He didn't try to apologize to me at school, or in anyway. Our 10 years friendship ended

And so time passed, I dated Monica for 4 months and then we broke up, high school ended and now I'm in college. But this thing still bothers me to this day. My mother told me that I should be the first to try to patch things up. She told me that so many times that I started to feel guilty. I'm not able to make any new friendships since, and I fell into depression. Am I the asshole for not trying to patch things up with him?

Sorry for my English, if anything's wrong
