I just had to add my bit ninja having 'been there done that (without the massive addition of the kids though)'
You do need to take a stand and make a clean break so the DDs start to come to terms with what is happening BUT do not beat yourself up on your coping strategies.
It is incredibly easy for people on MN to tell you what to do, that H is a twat and change the locks and be done with him.
The reality, as I remember all too well, is somewhat different.
My exH threw things, shouted, pushed me over, slapped me whilst we were breaking up yet I still went on holiday to India with him just before he moved out cos we had paid for the holida. There he pushed me over so hard he bruised by breastbone but that's another hellish story.
Thing is, when you have been in love with someone it is incredibly difficult to break all ties clean, even if you know it's the right thing to do. You don't just fall out of love with someone even if you don't love them anymore.
When he moved out, I felt sorry for him cos financially he had very little. I even paid for his cable TV for another 6 months as he couldn't afford it!
Yes, 7 years later I look back and gasp at what I did for him. But at the time it is very difficult to be the brave Amazonian 24/7.
So, what I am trying to say is, try your best to be the one in control but also don't beat yourself up if you choose the easy route to reduce your stress.
I think the idea of you going on the holiday while he moves out is a very good idea. I'm not sure changing the locks without telling him is the best way to go, although you are well within your rights to do so.
starlight wonderful to 'see' you again. I haven't seen any of your threads but I hope your DS is getting the support he needs (and that DD is thriving too).
Oh and ninja thanks to notcitrus and others, I am looking into reusable nappies and am joining a bf group for after the baby is born!!
Carrie what can I say - hang on in there. Go for a long walk if you can?
