I was always a bit like that as well. I lost allmy friends when I started dating and my onlyl friends where the girlfriends or wives of my man's friends...
I always wanted to spend time with him and wanted him to feel the same way.
I've been married for over a year and that feeling still hasn't gone away. However, you will have to do a few things, one of which you will need to hide your jealousy and obsession with him and allow him to have his life away from you. It's good for you both.
Try to make plans as well, away from him. If you have any friends plan on a "ladies night" and go out with them, don't call him when you are with your friends, and don't cancel on your friends for him. Make rules for yourself to, for example, only call him once a day for 12minutes... don't call him on Thursdays and so on.
It will be very hard at first, I know, but soon you will fall into routine and things will become easier.
One thing about men, they love a chase and a challange. Don't let him "catch" you (or all your time)...
Don't play games or act like someone you are not, but try to tone down some of your more jealous ways, if you know what I mean.
