Serial cheaters never change.
This honestly sounds a lot like what I went through with my ex husband. He only ever admitted to what I had tangible proof of, and every once in a while I would get this sixth sense telling me to check his accounts, and every time I’d find something backing up my suspicious feelings.
Im not going to tell you whether you should leave or stay, no one can make that decision but you. I can tell you that I went through it for nearly ten years, and I deeply regret not leaving much sooner than I did. I have young children, and unfortunately when I finally left I had just recently had knee surgery, and was out of work with no income. It WAS NOT easy, I struggled a lot, but I had friends and family that helped me out until I could get on my feet. My kids and I are doing wonderfully now, I know most people stay for the sake of the kids, but I can honestly say that me leaving has positively impacted my children, they are better behaved, they’re doing better in school, my oldest no longer has sleep issues or mood swings, and my youngest is finally speaking in full sentences after being completely nonverbal past the age of 2, and limited verbal past the age of 3. Now, take that all with a grain of salt, because there were physical manifestations of abuse in my marriage as well, in a perfect world I’d like to say I kept that hidden from my kids (save one incident that happened right in front of them), but who knows what they picked up on that I was oblivious to at the time.
The last straw for me was picking up my husbands phone when I was on crutches in his car and unable to walk unassisted. A notification came through and I was going to yell for him to come get it, but the notification was from Tinder 😐. I unlocked his screen and there were multiple dating apps right there on the home screen, as well as a few other apps that aren’t technically dating apps, that he had used to cheat on the past. I checked out a few messages (because apparently I needed more proof), locked his phone screen, set it down and crutched my way into the house by myself. He came in to see why I went inside and I calmly and coldly told him the marriage was over, I was done, he couldn’t talk me out divorce this time.
I’m so sorry you’re going through this. Multiple infidelities, and multiple DDays are hard to forgive, and hard to overcome. I got to the point where I resented my husband so much that I wasn’t even sad the last few times I caught him. I even made a few snarky remarks that he had so much practice, he should be able to get away with it at this point without being caught.
