Guys can be really dumb sometimes

I’m ready to give guys a break. So I had this friend (been friends since pre-K) and we’ve always just been cool. As we got older, we became attracted to each other and started talking almost everyday. Eventually we got together for some alone time and one thing led to another ( NO, we didn’t have sex😂). Anyways, now he’s ignoring me.

I’m honestly just mad @ myself. I kinda knew he was a dog, but i guess thought he wouldn’t do me dirty since we’ve known each other for such a long time🙄 but I guess all those years meant nothing to him.

Now every time I see him, I get really angry.

Any advice on how to get over this?
