My dd age 5 had a friend round for tea tonight. Her mum came to collect her at 5.30 pm and shortly afterwards my dh arrived home from work. It all went a bit mad and the kids went hyper. I had made us all a cup of tea and me and the mum were in the kitchen talking. Dd and friend were in the hallway harrassing dh and I could hear him saying, "no, that's enough, no more now" all that kind of stuff and I didn't think much of it. I'd had it for the last hour and so was a bit anaesthetised to it. I think he wanted to read something on the table and they were preventing him, as kids do when dad comes in. It got a bit embarrassing because the mum could hear him getting upset. She took the hint and gathered stuff and left. When they'd gone, I said to dh that I thought he'd been a bit rude, ignored the mum etc. He got angry and said that the kids had been hitting him and I hadn't dealt with it, I'd just sat in the kitchen drinking tea. To which I replied, I didn't know they'd been doing that but he was an adult and could deal with it. He said they had really hurt him and then I got a bit mad and told him not to be such a woos - they are only 5. With this, I turned my back on him to put something in the dishwasher and he said, "I'll show you what it feels like" and he lifted my top up and hit me as hard as he could on my back with all his strength. I was so shocked and the pain was so bad that I ran upstairs and lay on my front. My back was throbbing and when I looked in the mirror there were a couple of raised weals forming and I couldn't walk properly. Dd didn't see it happen but then had a tantrum about something else and then dh came upstairs, burst into the bedroom and said, "you've not bothered doing anything tonight, you deal with her, I'm going out". He then left and I struggled to get dd ready for bed. When he got home, I told him that it was unnacceptable what he'd done and that if he every did anything like that again, were were finished (he had previously hit me once on the back but not so hard). He replied that he wanted a divorce and would see a solicitor. I was so shocked that I left the house and when I got back two hours later he'd left keys in both the locks so that I couldn't get in. I called him several times but he never answered. By the time I got to banging on the door, he came down and opened it with a face like thunder. I'm too scared to go to bed and I know he will punish me for this because of his guilt. I'm strangely calm but feel really weird. What the hell do I do now?
