It was only like you gave him a ‘drunk dial’. Honestly, he should (and might have been) flattered. But for whatever reason he didn’t respond. Either he wasn’t interested in you or had other fears. You said he did ask you out though, so he was somewhat interested in you. So there was some disconnect and it was a long time ago.

I get why you feel embarrassed but it really wasn’t bad on your part. It was more rude of him to not reply at all but that may be due to his fears. So you’re even!

Give him a nice hello with your head held high. If he introduces you to his gf, just be friendly and casual. Oh, and look good, muahahahah 😉

I once felt mortified to run into a guy who I had casual sex with twice. It was a couple years later and he introduced me to the woman he was with, his fiancé. I felt so trashy. I never felt like that any other time. He didn’t act badly toward me. I slut shamed myself in my own mind!
