Recently, acted insecure with my GF.

Couple nights ago, while we were together, she was all over this gay dude which was very obviously an attempt to make me jealous so I didn’t pay it much mind.

Last night, she was really touchy feely with another dude at a party. He wasn’t reciprocating much but she was trying to make plans with him, was touching him a lot, and was catering to him the whole night.

When everyone left at the end of the night, I decided to leave too. She begged me to stay, tried to hold me down on the sofa, etc. she asked me what was wrong and I didn’t say much else other than you treated me like shit and I want to be alone. I mean she has to know what she did wrong right? And it doesn’t need to be spoken. I simply don’t want to mention it to prevent being seen as insecure.

She called / texted me a bunch on my drive home and tried to come over to my house as well.

I am not sure if her flirting with the other dude was just a nuclear test or if she actually wanted him.

She apologized a bunch over text, but didn’t say what for. And said she wants to stay with me and other fluffy words.

How should I proceed?
