Even last night, I went to sleep and he couldn't help himself from coming into my bedroom to wish me goodnight and give me a kiss and cuddle.
Hey Misty. I guess I'd reframe this statement (because you have control over how you respond/react) to read "I didn't stop him from giving me a kiss and cuddling with me".
You said in a previous post that you're not ready yet to enforce some boundaries. I suspect you'll hear many people here agree with me when I say that, until you do, things will likely continue "as is" if not get worse. Your H is getting to have a little taste of whatever lifestyle he likes and keeping everything just within reach until HE feels like deciding one thing or another.
You're also criticizing him ("It's hard to see what a younger, slim, pretty woman would see in him") so I wonder what you see in him that leads you to value him enough to continue enabling his behavior?
