I feel like it's over now (long post)

My best friend of 4-5 years finally found a boyfriend and I'm her friend online and I'm happy she found a boyfriend finally but when I see pictures of her and him her smile seems amazing and it starts to make me think maybe my time is over because she's starting to not talk to me a lot or at all and it's just feels like my jobs done..she had a rough few years of her childhood so when I met her I wanted to help her because she was in a bad state and I did it..but I guess I got what I wished for because at her lowest point I would wish and ask God if her life could get better even at the cost of me..it took a bit but she finally got better she's busy now and has a boyfriend so that's good I suppose but it sucks they all my friends or comfort people are in relationships because I feel like the odd ball now my cousin has a girlfriend my newer best friends are dating now and my older best friend (the one this post is about) is in a relationship so now it's just me and I try not to talk to them a bunch so I don't bother them
