Feels weird

I’ve been communicating with this guy (guy B) for about 2-3 weeks and I met him on Monday and saw him again tonight. After I left his place tonight, I felt weird. I don’t have any feelings for him so the fact that we’re hanging out like this (chilling, being intimate [not intercourse], and laying in the bed cuddling), makes it feel wrong and me feel weird. Not because I like someone else (in which I do ☺️, hence guy A) but because I’m laying up with someone who I don’t like and can’t see myself in a relationship with. Also, I feel like it’s not me. I’m a commitment, in a relationship kind of woman. Tbh, when someone’s being affectionate, I only feel 100% good about it when it’s coming from someone I like. I think about guy A all the time (even when I am hanging with guy B). We’ve been talking for 2-3 weeks, we have amazing chemistry, and he is such a gentleman! But I need not go on 🤤😍. And I’ve been missing him ever since he went home after finals week.

Thoughts/comments? Should I just leave the other guy (B) alone and give the guy I like (A) my attention? People tell me I’m single so I SHOULD mingle but I always end up thinking about Guy A and how great he is. I even feel a little guilty when I talk to other men bc I know I don’t like them, I like him.
