Re: How to handle this??
Two thoughts. One, it's great for your kids that you spent the last five years not dating. My mom didn't date after my dad left and that was a blessing for me and my self esteem.
BUT...them seeing you not date and putting two and two together - and remember that, to kids, you and their mom are their universe, so they watch every single move you make, and don't make - and are understanding that you are sitting there, pining away for mommy and mommy not giving you the time of day, until now. Trust me, they'll find all this out. And what are they learning? That men are whipped, women are cruel and selfish and use people, and that is how THEY are going to turn out, because we all turn out like our parents. AND, we end up searching for partners just like the parent who hurt us worse (see the book Getting The Love You Want to understand this). So not only are they getting skewed view of weak men and cruel women, they will end up picking one for their partner - unless YOU step up and show them what a healthy, happy NON-whipped father acts like.
