Hey BBJ, I did not want to rile you up with my post. I do not want to pile on but let me just say that i agree with you on all counts. I am a pretty normal guy ....at least i think so. What he did last night (as you described it), I would not have done to my ex mother in law(you know how much i like her), never mind the mother of my kids.
BBJ, I know you do not want to hurt the kids but you are letting Dan off way too easy as it pertains to his weekend on the calendar. It sounds like his weekend on the calendar is you guys doing family stuff together and then he just leaves without the kids. I think I agree with K above. As hard as it is for you, you need to get a little tougher. Use the weekend for BBJ. If you absolutely want to do the family stuff, do it on YOUR weekend.
have a nice Sunday BBJ.
