Can people please answer this question! I wanna do it today but I'm not sure?

I really miss my friend .. we haven't spoken for like 3 months cause we kinda drifted .. only cause I would tell him my problems at the wrong time , ( I would call his phone at 5 in the morning just when he got home from work & falling asleep) it wasn't on purpose I just had alog of family issues.. and then we really stopped talking 2 months ago because I thought he was being fake and showed this guy I didn't like something of mine & we kinda went back and forth. I really miss him & he was like a brother to me.. litterally. He would take me home even if it was 6 in the morning, I would cry on his shoulders , you name it ( we was strictly friends only because I was dating his best mans before I knew him we all worked together) should I message him & sincerely apologize ? I'm not sure because I don't work there anymore but I miss him
