How can I get over my crush?

We’re very close. Known him since we were kids. He tells me everything and I do the same. In fact his mom text me weekly. I can’t just cut him off. But I love this guy. And we can’t be together. I don't know how he feels for me. I know he had feels a while back but I was never single. And I won’t ever ask. So how do I move on?

i can’t stop myself from looking at his Instagram. And each time he adds a girl my heart breaks. Then today he followed the page about college and girls in thongs. Lol. It’s so upsetting.
