Though it might come off as malicious and bad to you, this is solid advice. At this point, you owe her and her feelings absolutely nothing. For our own good an emotional stability, I recommend following this advice. You don’t have to follow it to the T but the premise is sound. Take her out. Get her head and heart in a good place. Express to her what your relationship means to you and what you’ve done to appease her while part of it. Present your evidence. Dump. That. Bitch. Peace out. Don’t look back. Block her. Cry it out if you have to. Dust yourself off. Move on worth your life.
I’ve dated “her” before. Get out while you can. You and your own feelings should be more important to you than her and her feelings. Love yourself, homie. Do the right thing.
Good luck. Be prosperous. Godspeed.
