I really need a bit of perspective on this one, I'm furious at the moment and finding it hard to bite my tongue as I would usually do.
First of all, I'm a stepchild myself and experienced similar threats from my own mother which I think is fuelling my anger right now.
Today Ex asked DP is eldest DSS (12) could come here and stay for a while. DP said of course and asked if everything was OK as the message was worded in a very peculiar way and it is rare for only DSS1 to come without DSS2. In the 2 hours or so it took ex to respond DP managed to get himself quite worried that something was up but ex text and said all ok. A couple of hours later she text to say he wouldn't be coming after all. It's emerged that she was using coming to stay here as a 'punishment and a consequence' of bad behaviour! However 'it worked' and now DSS has learned his lesson.
DP said he is their father and not a punishment to which she replied that she could do whatever she likes (and a load of other abuse).
My own mother used to do this to me and, as much as I adored my dad, I lived in fear of one day being too 'naughty' and being sent away from my home. It really affected me and made me terrified of ever doing anything wrong in case I was kicked out.
I hate the thought of DSS feeling like that. He's a lovely boy and going through enough as it is without that threat of being sent away to dads if he doesn't behave hanging over him.
I keep out of DP and ex's squabbles (she's being vile to at the moment but by next week she'll be over it and he's so desperate to avoid her wrath he goes along with it), this one has really irritated me though.
