I had to call the police on DH and he left as soon as I called them.
Stupidly, I let him come back after they left as he seemed truly sorry and, stupidly, I felt sorry for him as it was very late in the evening. But I told him we were over. He refused counselling and I gave him a month to show he could change (deep down I knew he couldn't - he thought it was me backing down).
The next day we went out as a family because I couldn't stand being in the same house. He tried to win me back, put his arms around and so on, but I kept telling him it was over.
Over lunch, he kept mentioning that I had called the police in front of DS (he hadn't witnessed anything) and basically blaming me for it.
That night he was upset because I slept on the sofa again.
The next day he went on a rant basically threatening me if I left. I didn't respond. He then threatened to take his life, along with mine and DS's.
I took DS away, went to the police and the police told him I had left him for good when I tried to pick my things up. He then threatened to commit suicide and the next days and weeks were hard.
Your STBX is following a common script and I'm worried that he may be dangerous for you.
Again, I would urge you to get an injunction or no-molestation order. Check NCDV 0844 8044 999.
And remember that you can get legal aid if there is DV.
