fell inlove with my bestfriend

i had a crush on him when we first started talking,i confessed but he didnt really give me a response?the feelings quickly faded away,though. we continued being friends. we grew closer and became bestfriends,i shared everything with him,he shared everything with me. he got a girlfriend,though. he fell inlove with her and she forced him to block me. i totally understand that..but it hurts. literally whenever i see them in public,theyre making out or touching each other. it makes me feel..sad. and disgusted with myself. everytime i see her reposts about how affectionate he is,i cant help but wish that i was in her position. he often views my profile,like maybe 2 or 3 times a day,im reading too much into it. he asked me if i miss him and i said yes,i askes him if he misses me and he said "not necessarily, but i think about you often" well shit,ho
