Well, I had finally had enough and told the other half to pack his bags and leave. He obliged, but only to go to my sisters for 1 week - an attempt I am assuming to try and apease me. Only I know and he knows that it takes at least 2 weeks for the stuff to get out of your system, let alone sort out the reasons why he is on it in the first place.
Another crucial fact is - that although the childcare has been an issue I have managed to get through it and we have had a thoroughly nice time and haven't missed him at all. He hasn't even bothered to phone. Which is good news as far as I am concerned, but I thought he may have phoned the children!
So all in all it has only baulstard me on to have a life on our own. Onwards and upwards!
