AIO Wife keeps hiding phone

My wife keeps hiding her phone when I’m around very obviously, changed her passcode, and removed my Face ID. I had many conversations and arguments and tried so many things to figure out why. I tried taking her out to nice places to talk etc etc. I even tried therapy and she is not improving at all and still being secretive.

She was not like this at all in the beginning. I don’t want to believe she’s cheating on me but everything is telling me she is. There’s absolutely no way someone should have that type of reaction, especially out of no where, when I’m around her.

I talked to couple of my friends and they just laughed in my face and told me she’s obviously cheating. Our therapist just kept mentioning to me on how she has a lot of trauma and that’s the reason (but she was never like this before with me). I’m I over thinking this???? Her excuses is that I’m crazy and she said she doesn’t want to give me the satisfaction. I never questioned anything until she was hiding her phone when I’m NEARBY.

I don’t want to divorce. I already done so much for her and went through the most toxic stages of my life. It feels like she gets a kick from making me feel a certain way. I’ve caught her texting her ex multiple times at the beginning of the marriage which is why my trust is horrible towards her. Till this day she calls me crazy about that
