@rubyskye910,
You broke up five months ago with the father of your children and have started a new relationship that you believe will lead to marriage.
I think it sounds like you need to put the brakes on everything.
Take a time out and get to know yourself better.
No dating. No reconciliation.
Focus on work, your children and yourself.
If the new guy is as great as you believe, he'll still be there after you've taken a good time out.
I suggest at least 8 - 12 months on your own. No dating. Just you, your job and time with your kids. Take some night courses. Upgrade your skills. Decorate your house/apartment. Figure out what you will be doing with your future - with or without a life partner.
Seriously. Cool all of it down.
