Hello novachick99!
I really hope that the talented people of this forum can help you out with your problems. I have been in the same seat as you and I know that most women has been there too.
There are several different ways to do this. There are a lot of different things that you can do with your behavior around him that can change him and make him love you more. I will try explain one of these "techniques" a little more. I have tried this myself several times and now include this in my dating life.
I suggest you try a technique that is called "the respect principle". It is based on a study conducted by Shaunti Feldhahn made in 2006. I'll try to explain the respect principle in one sentence: "The majority of men would rather give up your love, than lose your respect for him." So ask yourself, do you feel like you've lost respect for him lately? If you have, maybe that's where the problem is. I have actually written about this on my website (in my signature) if you want to read more about it.
Good luck!
