Flirting Fears

Guys PLEASE do not downvote, if you have an opinion or feel like I'm reassurance seeking, then tell me in the comments. Downvotes make me unnecessarily anxious because I don't know what they mean.

So for a moment there I thought my boyfriend had cheated on me because there was a misunderstanding. I went on break, and on my break there was a guy who I used to have false-attraction OCD about. He is very nice but I don't find him very attractive, but during this situation my OCD latched onto him and thought about him as what if he was a rebound if things go bad with my boyfriend... and in the next few moments he was trying to plug in his charger but the outlet was behind me, so I offered to plug it in but then realized there was a charger behind him so I pointed it out.

I spoke to him maybe one other time but that was it then we just sat there silently because I didn't want to talk to him.

But my OCD is making me go crazy over this. Because I was thinking about a rebound or flirting or the potential to date, I feel as if I've somehow flirted with him by being nice.

I just can't even make much sense of it

But it's like...

If I had an angry thought in my head and was mean to someone because of it, that would be me being mean

If I had a thought of hypothetical scenarios of dating while talking to someone, wouldn't that mean I was flirting?

It's like. I feel like I was thinking to be nice for the possibility but I don't know. I just am so stressed and confused and feel so guilty because I feel like I really did flirt with him
