Hubby is ten years older

And I feel like it makes me feel like he’s more mature and makes him insecure. We’re supposed to be getting Married in two weeks but I don’t know if I want to. He’s overly possessive. Always thinks I’m cheating. I am NOT!! Checks my phone when I’m sleeping 😴. I did the same today and I found so much pictures and screenshots of things on my phone. It’s stupid things like that. And the anything he finds is irrelevant. It could be a funny iPhone and he assumes it’s mines! Reads my messages from family members or me and my gf talking shit. I’m in love but I’m also not stupid. I don’t want a life like this.
