I'm going to admit I didn't even read what started this "off-kilter" type discussion, but I did perk up a bit at "band-aid" and wanted to chime in.
Anyone can feel free to flame me, but I honestly feel that a guy can do everything right to get his life complete and happy on his own, and still need someone that's a little bit of a "band-aid". Being 10+ years out from my 1st divorce, looking back I still think it takes the kick of interest in someone else to completely shed those last little tendrils of "what ifs" that surround the ex-spouse. Maybe it's just me...does any other GUY (sorry ladies, I'm just not sure you are wired the same way) have a similar feeling or am I just weak? Anyway, I'm saying that if you've been up front with this girl that it's fine to date.
Were your worries how your kids would react to that? If so, I can certainly understand that. I didn't want anyone around when I was spending my time with my kids (that won't work for you if you have them most the time) and really felt nervous and bad for them when they had to share my time with a new woman. Anyway, I'm just blabbering.
