Well the proverbial manure just hit the fan....apparently NGF was redecorating the house and decided to take down some family pictures (with her ex husband). Well both kids reacted badly...the son now wants to move in with dad for the rest of the summer. Something tells me they (the kids) won't even last the scheduled week (next week). I have been through this stuff before with my step kids from my previous marriage. Anytime there was an argument with the mom, poof straight to dad's. I told NGF this and also suggested that we seriously limit our interactions between each other in front of her kids. Also suggested that it was pretty obvious to me that both her kids are struggling with mom seeing someone and that she should consider some professional help for the son at least....I tried to be as understanding as possible. So there you have it, no horseback rididng this aft. I decided to cancel that outing and any other outing involving her kids ... for a while. Any feedback on what to say to NGF and if I am doing the right thing is welcomed.
