There is no right or wrong in this situation, It doesn't even matter at this point, you made a decision as a man and you felt like you was right in that moment.
Now to the important part, what are you going to do about it? The way I see it, you got 2 options.
1. Apologize and go to her and make things right however way you see fit.
2. Stand your ground and be willing to accept losing her for good.
Dont try to protect your ego and let your pride make you sit in the corner and watch something you want in your life walk out. Me personally, I think this whole situation is petty as hell and very immature.
No reason to be passive aggressive, if you legit don't care(which I know you do) then fine, go meet another woman, but since you do care just give her call and tell her to come to your house so you guys can talk, work it out then have crazy hot make up sex
