<human>: My guy and I dated long distance for a little over a year. We stayed long distance until after our engagement began, at which point I moved in with him. Prior to this, the newness of the relationship began to wear off, but I thought moving in together would help. It did, for a bit. 

For months now, I have been struggling to rekindle the sexual and emotional attraction I once felt to him. I love him, and he's an incredible person and a very logical partner. Our differences aren't many, but enough that we can happily have parts of our lives that aren't constantly entwined with each other's. Separate hobbies, etc.

I never just want to pounce on him anymore. I find myself feeling intense sexual and sometimes emotional attractions to others lately. I have drastically reduced contact with the subjects of those attractions and am trying very hard to consider my SO in positive light always.

I also sense sometimes that he is doubting our relationship. He is not the type to share all his thoughts and emotions, so he is a mystery to me on these issues. In the last few months he has made the following two comments "are you sure you want to marry me" and "I worry you'd be happier with someone else" and I'm not sure whether this is an expression of insecurity because he's noticed a change in me, or if he just wants me to leave but won't say it. He's got strong moral convictions and in the past resorted to "being the bad guy" so he wouldn't have to break up with someone.

What can I do to feel more emotionally connected and attracted to him? How can I feel more sexually interested? Am I being silly for worrying he has checked out?

(I should note that his body and appearance has not changed, he is the same guy with improved emotional maturity now, and he makes more money now than he did before. No negative changes have occurred. Help!)

Can you provide a brief overview of the text?
<bot>: Decreased attraction to SO and catching myself with a wandering eye. He seems to have caught on and is doubting me, which upsets me and makes me wonder if he's checked out too. How can I fix this?
