@Arnoldsgirl3,
How long have you been seeing him?
The distance him to you 2 hours? Thats a bit much to get close to someone.
Things have changed. Something has changed for sure. Tell him you noticed a change in pattern. Sex, conversation or lack of, time together, goodnights goodmornings stop, lack of interest. Just ask him, and tell him you notice a pattern change.. cause that is what you are seeing, you are not wrong on that, and there is something going on. In the meantime I would hold off on sex until you figure out what is going on. He will be black and white and get to the point if it is you two just for sex or not. But could be other things
Cold hard truth is he could be loosing interest. My initial though is the 2 hours away.. but there is sex. See where I am going? Not all guys are the same of course, but it does sound like it could be a case of girl on a leash.
