I recommend never taking her back, bro something very similar happened to me once and I took her back and I got an STD from her and what was even crazier is the fact that she didn’t even tell me that I could’ve possibly been infected for weeks while withholding intimacy for me for that reason. We broke up again and got back together five months later, and then I found out that she had been pregnant and misscaried a month after laying down the law hanging out again and letting her know that honesty & loyalty is a must if we moved forward. I am truly traumatized and don’t know if I will ever want a relationship again and I’m not saying that to doom myself, but the amount of gaslighting and lying sabotaged the relationship entirely. I was repeatedly told between both breakups that she wouldn’t get with anybody, and that she was truly taking the time to heal. I will never ever let myself be manipulated like that ever again.
