Ugh!!!

I'm kinda regretting this decision and this is probably gonna make me sound bad but I had the opportunity to hook up with this guy that I've been lusting for since high school lol he was rubbing my shoulders combing his fingers in my hair started kissing me down my neck and I'm thinking hell yes but then I remembered he's my bother in laws best friend and he's drunk so I stopped it because I'm not the one to take advantage and I figured my sister would kill me and I didn't want him to start acting awkward around me I didn't find out till later at home when my sister came to pick up my niece that she would of been okay with it because she thinks he's a good guy but now he's left town gone back home and I'm totally regretting stopping him like I know it was probably for the best but I also hate that I did it lol I'm horrible
