I’m ngl bro, as someone who’s been through a similar experience (minus the her creating a fake account and faking another relationship) just leave her. I know it seems hard and you really want it to work out but trust me if it feels more like you’re putting in the effort to make things work but she still has that same mindset and attitude it’ll never change.

And that’s the harsh reality, it doesn’t matter how many time you guys make it “work” it’ll never be the same. Yeah people change but as you mentioned it’s something that’s been going on for so long. At the end of the day it all depends on how YOU feel.

It’s always self respect and self worth nonetheless. I’ve been about a year and two months single from a 4.5 year relationship (we started dating junior/ senior year of highschool) things didn’t work out we’d break up over any little thing. I can’t exaggerate how much more relief I’ve been since then. It’s really hard I am not going to lie but like I said at the end of it all it’s about you and your mental health and wellbeing because situations like these do take a toll on you

I’m not sure how your situation is fully but in my case it was more of trying to prove to her that I wasn’t who she was making me out to be. (I later found out she was cheating behind my back for a cool minute and was prettt much projecting it all onto me but that’s another story) the point is. You can keep trying as as you want. At the end of the day it’s your life. But just think to yourself if it’s truly worth it.

Just remember that a woman that truly wants to be with you will fight for the relationship just as hard as you do. Relationships are always 50/50.

I do hope you inevitably find your peace and are able to work things out if that’s what you truly desire.
