Help me out, sis!

(it's kinda long, sorry about that!)

So, 2 months into liking a guy, I straight out told him that but he said he didn't feel that way which was a bit unsettling because the way he talked really made me feel that he liked me, too. And I don't think he would intentionally make me feel that way 'cause he is genuinely a good person.

We're still friends. I don't see much of him in real life but he often posts pictures of him and his girlfriend which obviously affects me. And blocking him would be somewhat immature, I feel.

I have even met a lot of amazing people still, I always end up comparing how they make me feel with how he did and he would always outshine them.

It's been 1.5 years of me liking ('like' is definitely an understatement) him but I still don't know how to get over him. What do I do? TIA Y'ALL ARE THE BEST ❤️
