How to deal with girls you tried to approach when you already have a GF.

[Sasomange]

Long story short, one year ago a girl fucked me up really hard - I was emotionally down, and it took some time to get back yada, yada.

In the meantime I started gaming, following Todd and Max and watching their courses. I am not exactly a confident guy so, through a lot of trial and error I kinda found myself (I got up mentally).

The issue comes now - I found a really cute and nice girl that I'm together with for 4 months now. She is currently leading a very popular NGO here in our city and a lot of girls that I approached (both successfully or non successfully) kinda hang around my GF, at least 3 or 4 girls.

How to deal with that - approaches with some of those girls went really, really bad considering that I was still an amateur and also really lacked confidence. My girl calls me often to parties that the NGO holds but I'm kinda reluctant to go. My biggest issue is ego related - I dont want to be classified as a weirdo or a guy that picks up women, if they talk between them.

Thank you for your answers guys, and all the best!
