"I said I do have plans but had arranged for a sitter. To which, I kid you not she tells me it isn't appropriate for me to be dating."
How dare you have a life? Did you not read the rules? We LBS's are not allowed to get on with our life. We are supposed to be laying on the floor wallowing in our grief because the most perfect one has left us. We are not allowed to have a life until they grant it so, but be aware they can take that back several minutes later. But seriously, if you just lost it, then you still got some work to do. By her words making you lose it, proves to her that she still has some power over you. Probably a more appropriate response next time will be "whatever" turn and walk.
"So I had S last night and it was terrible. He acts up all the time now and then just shuts down. He cried all night for "mommy" and won't let me touch him or hold him."
I am not remembering the age of you son, but I am thinking he is younger than my daughter. I have been going through some similiar stuff with her though. She is 5 1/2. The other day I took the store got her a toy, took her to a childrens type a place to play, took her swimming, and then we went out to eat. On the way home she starts throwing a fit because I wont take her to WalMart and get her another toy. "You are the worst dad ever. You dont care about me. I hate you." Now it seems like she can sense when I am really tired, and bugged by all of my crap. We were driving at the time. I did get mad, I told her, "All of the things we did today? I cant believe you would say that. Your words really hurt me. If you want to act like that, I dont even want you to come see me. I really wish things were not like they are. But if you want to say things like that, just stay with mom, dont come see me."
She got quiet for a minute, then said, "I am sorry, I love you"
She is having a harder time coping with this then she lets on. I need to probably be more assuring to her. It is hard being that single dad guy sometimes, isnt it???
