The only one that was true in my case was number 1... but it was so gawdawfull, didn't matter much that the others had nothing to do with me and my kids.
.... that is till I met my husband.
Single moms are definitely not to be trifled with and I never EVER took offense if a guy opted to pass on dating me because I had children or just because of the sheer number (I have four).
I had guys say that they wouldn't consider going on a date with me when I had four kids. Totally acceptable point of view, except this one time I thought it odd as HE HAD FOUR KIDS TOO! LOL
