Cheater phone habits

Ok ladies so maybe im just trying to prove to myself that im not paranoid. So long story short my SO cheated and all that stupid shit. When I found out I went crazy was not in the right state of mind (not making excuses for myself) and ended up talking to a few guys over a couple months span, never slept with anyone and cut ties on my own accord way before he found out cuz I came to my senses and knew it wasn't right, anyway, he found out and was very verbally, emotionally, and mentally abusive towards me. I left and he begged me to take him back. I foolishly did for whatever reason. Fast forward to now his phone habits are still The same He has his phone on silent all the time except for when he's not home. He takes his phone with him to the bathroom even tho he knows it makes me uncomfortable (he would send dick pics to girls while "using the bathroom") I caught him the other day at 3 am coming to bed from "using the bathroom" with his phone. He made the excuse that he took it just to use the flash light so he wouldn't trip and fall when I have motion night lights through out the house(we have kids who get up at night) I've just been having this gut feeling but can't seem to decide if it really is my gut feeling or if im just insecure, obviously, from the damage he caused in the past. He also has a password on his phone and I seen him hid his phone screen from our daughter when she sat down next to him. Oh and for some reason I found numbers in his wallet that he had written down and they ended up being numbers from my phone that I had blocked (telemarketers) so maybe he is showing signs of a guilty conscience? Idk. I have herd of cheaters having certain phone habits. I guess I'm looking for women that have had similar situations and see if there is in fact something to follow this gut feeling.. Thank you to the ladies who are willing to give friendly non judgmental advice. As for those who just want to criticise and judge, you can miss me with that bullshit thanks😘
