I was at a party and I came across a girl I was friends with. She was alone so we hungout and she'd laugh at nearly everything I said and I did some light kino in between and she was extremely receptive to it all.

Occasionally while we were talking I'd just up and leave and she'd follow so I figured things were going well.

Eventually some older guy came in and I noticed he kept touching her and she tried to reject his advances (I think it was because she knew I was watching) but as time went on she stayed with him and she stopped following me around.

So I did my own thing and tried to game other women (it was hard since most girls were taken there), she'd occasionally ask how I was but I just kept hanging out. If I'm being honest I did want her to come back but she didn't so I just played video games with friends while she was with him.

When it was time to go she ran up to me and said "just leaving without telling me?" and hugged me. The guy must've noticed because immediately after he went in for a kiss, idk if they did kiss or what but I think they did.

When I got home I blocked her on Instagram and erased her number. I did the right thing right? Probably should've made a move quicker, but that guy definitely seemed to be mate guarding hardcore and she seemed more into him.

TL;DR: I was hangout out with a friend at a party and she was receptive to kino and would follow me around. Some guy came in and tried to kiss her, she denied it at first, but eventually went back to him (I think it was when she was more drunk).

I just did my own thing and tried to game other women (she saw me talking to some of them), when it was time to leave she ran up to me and hugged me. The guy immediately went for a kiss when he saw her hug me, I think she did kiss him. When I went home I blocked her IG and her number. Did I do the right thing?
