I’ll make it really short due to the character limit.

I started working somewhere new a few months ago, developed a crush on “Blue” right away. I’m shy though so I just shoved it in the back of my head. Few months later, a girl(Purple) gives me her number. We start a relationship 3-4 weeks later. Really like her. It’s still going great. Me and Blue start eating lunch together, due to me showing concern for her one day, despite her insisting it was just an upset stomach(turned out to be pretty ******* serious). It’s just friendly lunch, never any flirting but I’m liking her more and more. Although I would never do anything to be unfaithful, I feel guilty for having feelings for someone other than my SO. I don’t want to hurt Purple and I don’t want to end a great friendship. But I feel like it’s becoming more and more clear that I like Blue because of the way I act. Uh?
