He didnt really want me until I left his ?

Its truly something that NEEDS to be discussed. You need to have someone watch the kids and have a time set that the both of you can go somewhere and talk. It's the rest of your life and your children's lives that your dealing with. You may love him and he may love you. But marriage is not something you should rush into. You need to be sure. And then you need to go back home and before making any marriage plans, see if his tune changes. If he's serious you'll see it. I was with someone for 5 years...it was hard to leave but an unhealthy relationship that I was unhappy in....it hurt to leave, missing the things I was so used to, and comfortable with..... but I did what was best for my health and future.
