Hi there -- I have been in your shoes, almost at that same time in my life...I had 3 kids from 2 different dads and I just decided then that I had a bad track record and would take a hiatus. No dating for 6 years. But I yearned to have more children and live a more traditional lifestyle for my family, so I remarried when my kids were 7, 9, 11. Although my dream came true of more children (5 more..yay), it has been a hellish blended family experience. All 3 of my older kids wish I hadn't remarried though they love the little ones. My point is, (AT THE HUMONGOUS RISK OF PREACHING) unless you have a burning desire for more kids, which is the point of marriage, which is the point of dating, be the strongest mom ALONE you can be, speak kindly of your ex and encourage him to be the most awesome dad he can be. Sacrifice the joy that dating can bring to your life for the sake of the emotional fragility of your kids. Of course, if your husband is like Bruce Willis, and you can find that Ashton Kutcher, haha.....sorry, I just watched Letterman last night..seriously, tough decision to make, but that sacrifice will mean so much to your kids. whew. Good luck!
