My DP cheated on me nearly 3 years ago now. Some days I'm okay and then some days I turn into an insecure crazy person and tell myself horrible things and why this woman was better. I know it's nothing to do with this woman, she didn't even know I existed. I keep checking her social media, it's awful. I feel like I should be over it by now, surely? How long does it take? I never bring it up because I don't want to cause an argument. I know he's not cheating on me anymore of course that's hard to believe but 99% sure. I just have this worry for some reason that one day it will happen again. Is this a sign that I'm never getting over it?
