Lost friend

Do I always need closure from the person? Once upon a time, I thought my best friend was my soulmate. I thought we would go on trip together even after high school and we would always keep in contact. Knowing the past me, I had a problem which I communicated that I like consistency and I would like a weekly checkup especially if you’re posting and I’m your best friend. I knew she had to branch out and I was a little upset bc we had just graduated from middle school and made our way into high school. We went to two different high schools but in the same city. We barely talked over the summer but I tried to make plans with her bc we said we would after graduation. She was always too busy but would post her going out. She met new people at her school, and we barely talked. I still followed her at the time but what made us really stop talking was no of miscommunication. In a gc we had, we had a mutual friend who was attention seeking in a way and accused my ex best friend(we’ll call her s) of not liking him anymore bc he doesn’t text her anymore. I replied in the gc to text me or whatever about that. And he did and I explained to him that she has a life and at the time ofc I was hurt and upset at s but I wasn’t going to do some bs excuse just to get the attention he wanted. So I explained and she thought I was taking 💩about her when I wasn’t. So after that, she unfollowed me on everything and we just never spoke after that. I do miss her and the fun that we had and now whenever I see her, she looks away from me and tenses up. I go to her work sometimes bc sometimes I wish she would just confront me and we would have a talk. But it’s been four years. I do wish for that friendship back bc I kind of feel like it wasn’t the right time. But idk if this is the right time. Idk if I hurt her but ik she hurt me. And idk if I should try to talk to her about something that happened four years ago or just leave it bc there are times where I just miss her and reminisce and think about talking to her. Idk if she feels the same way. But the thing is, I am friends with someone who she doesn’t like (we’ll call her d) bc of what d did to s. S bf kissed d when they were together at the time and I didn’t know until I was friends with d. Idk if she won’t talk to me bc of that but we have another mutual friend with s who I barely talk to but we are friends. Idk if I should go through him to get to s bc they go to the same school and work at the same job. But the only chance that I would the both of them are at their jobs. But I work when they work and would only have 30 minutes to get there. I may be doing too much but it’s been four years. Idk what I should do.
