I have a few plates. I'm very busy and only really go out on the weekends to socialize.

I have tons of women with rings that give me overt IOIs.

My question: How do I escalate with women that have men who are clearly interested?

I'm not referring to married women. That's a shit hole I'm not trying to climb out of. More so women with men. In front of their partners they will be very overt towards me with their IOI. Usually I just ignore them and carry on, but lately it's been getting more and more frequent.

(I have made a life for myself that enables me to constantly working on myself).
In the face to face interactions with their males around most of the guys are billy beta blue-pilled provider nice guys that can't even tell what is going on. I'll flirt a little back through body language and more covert indications. There is still a blue pill part of me that doesn't want to "take this guys girl right in front of him" even though I know it's just his turn, and she's not that interested in him.

Women with a boyfriend will come on to me very strong. I know for a portion of them I'm a fantasy for them. Most of them are regulars at my business so they're out of the question as well. This is more as a broad concept to be applied to applicable scenarios.

TL;DR: How to overcome the thought of "don't steal another guy's girl", and how to escalate keeping myself in the zone of "plausible deniability"?
