I had one that would frequently go out with me to my favorite venue (I've since dumped her and gone no contact)

I leveraged it wrong because I was an idiot. I would only dance with her at my country venue I go to. I would let other girls steal me here and there but I didn't go out of my way to capitalize it.

My situation was unique because with dance I can show her off and thus, show myself off. There were girls that were into me that stopped getting a chance to really even spend time with me some nights and some would desperately look for an opening all night

One girl was searching around the whole place as soon as she noticed my FWB wasn't around me any more (she had to help her cousin who was throwing up)

Other ones got angsty and were desperate to get my attention. I was dancing with her and this 9 who I kept ignoring was literally dancing with another man and she shouted "hi VRx!!!!" Quite loudly on the dance floor as she passed me.

While she LITERALLY had another man dancing with her. Dude was reasonably high SMV and just looked deflated after that.

On the nights my FWB wasn't there they would swarm me. They still kind of do actually. I think it made them realize I can be taken.

Now that I dumped my FWB (was stupidly exclusive) I am trying to follow up on leads I missed out on, including the 9 who still shows IOIs but who I might have lost some attraction with

My situation was, again, unique. It was a social scene with specific norms and expectations so it wasn't JUST a place to chat.

There's almost an expectation to spend time with multiple people of the opposite sex there, it was normalized to ask even taken people to dance, and these were girls that previously danced with me before I was with the FWB, plus, she wasn't always there with me.

So they got angsty and desperate a lot.

Unless your scenes have dynamics like mine, you may be best able to capitalize on throwing bread crumbs at the other girls when you and FWB are there and then go hard when she's not there on the girls that were ansgty for your attention

My FWB was "pretty" (as guys and girls described her) and looked like a 7.5 with makeup. she wasn't HOT but people thought she was hot enough to congratulate me.

Yours is 7-8 so it might help

Now, it WILL hurt you if they think you're taken. You're playing with a double edged sword. Some girls will see you as desired but also lose interest because they've decided they can't invest in you any longer because you're taken. And they'll drop you as a prospect

I told girls she wasn't my girlfriend so they kind of held out a bit. I have a new plate/FWB already that I had to ignore when I was with the old one and she wanted me the whole time apparently.

You're mileage might vary but it sounds like your bars might or might not have the built in dynamics and advantages mine had. I don't know what kinds you go to
