I might have lost the love of my life

A few years ago I met this guy on Instagram. When we first started talking I thought he would just be someone to play around and mess with. Eventually we ended up becoming best friends. We had a strong relationship and were really close. I started to have feelings for him and they stuck. We ended up having a friend/ lover type of situation. Long story short we stopped talking after we each found some stuff out. Then when we did start talking again it was after a breakup and I truly believe I was just looking for comfort. When he wanted to talk I never had time and pushed him away. Then he posted on his Snapchat New Years that anybody that hasn’t talk to chin in forever he will pretend like he never knew them I took it personally. Now i realized that I fucked everything entirely up and I don’t know what to do.
