How to move on? Help.

I was talking to a guy for two months, and had a crush on him. He seemed like not interested after we had sex.

So I asked advice on here.

I deleted the guy’s contact on everything.

I keep thinking about him. Fml it’s hard.

Don’t ask me to keep myself busy, I am a busy person, but I cannot stop myself thinking about him even if I had a break for 5 mins 😭 now that I’m in bed, it gets worse.

Please help girls.
