Codependency or fear of abandonment?

My husband is so suffocating, it’s beginning to draw me away from our marriage! I can’t exit a room without him questioning what i’m doing or where i’m going or him following along. As someone with an introverted personality, I value time with myself just as much as I value the time I spend exclusively with my husband, but there are absolutely times in which I need a “breather”. I just want to relax in a different room of our home and read to myself or enjoy any of my individual hobbies, but I can’t! Imagine your 3 year old following you to the bathroom, to the kitchen, having to tag them along everywhere you go because they’re dependent on you, but instead it’s a grown adult with co-dependency issues or perhaps a strong fear of me leaving him, both of which I have no control over. Yes, we’ve spoken about this multiple times, but he still takes it personally or it makes things awkward.

Sometimes I try to escape from bed at 1am at night when I think I’m certain he’s fallen into a deep asleep assuming by his snoring, but he immediately wakes up and starts asking me where i’m going, even if it’s just to use the restroom. He’ll lay his hand on my shoulder while sleeps just to be able to monitor my movements in bed and to know when or if i leave the bed.

I understand the way im describing things it may sound like toxic behavior coming from him, but it’s not. He has an unhealthy clingy personality, but one he only started developing after he cheated on me and stepped out on our marriage after the second time of being caught. He’s never been this way up until that point. Wanting the constant affection, always wanting to be in close proximity of me. I don’t think it’s genuine, and that’s why I don’t like it anymore. I would’ve loved this version of him about 2 years ago before I felt like he only started being this way in order to make me feel like I’d be leaving something behind if I ever left him for his infidelity.

I know I can’t be the only one with a spouse like this.
