@Honestbluebell if you would like to pm me, my previous career was medical and I may be able to provide some reassurance.
I'm OK. Yesterday afternoon was quite difficult when H arrived back to spend the weekend with the DC. He was a mess - shaking, rocking, hunched over, wearing odd clothes that were too big for him, frequently screwing up his face as if in pain. He started begging me to change my mind again. Saying he could change and that he was changing already. He said his DDs (23 and 31) have both said that he has changed already so this is proof that he will be able to do it. He said he had got anti-depressants and that the Dr had told him these would help to sort out his anger as well (!).
I just looked at him and felt angry for the first time. I told him that he needed to pull himself together to be able to be an effective parent for our DC, otherwise I would not be going to stay with my friend.
A few minutes later he came upstairs and asked if we should tell the DC. I was a bit taken aback at this as it was the opposite of what he had just been saying so I said I hadn't prepared to tell them today and that I felt it was unfair on them to tell them such momentous news and then walk out. He said - well I don't want to tell them and walk out either. I pointed out that it would be more unsettling for them for me to be walking out as their primary carer. He went silent at that point.
After a lot more backwards and forwards, more begging, self-pity and emotional blackmail he said he felt he would be calmer and more stable if I weren't there because all he wanted to do was kiss and hug me. I agreed to go on the proviso that I text DS1 later that evening to check up on them.
Had a lovely evening at my friend's house - her DSis has a long career working for Women's Aid and it was therapeutic to be able to talk to her. When I text DS1 he said all was fine.
This morning I have messaged him again but no reply, so am a little on edge now imagining all the awful things you hear about in the news when men go crazy but I'm trying to get a handle on that because DS1 is not the most reliable communicator.
