uknowme, i have had it happen to me and not happen again.
very similar to waht happened to you, last august both me, DP, and our first son were staying at his dads house for the night, after we had been out with his father and stepmother, my partner was a bit drunk, i decided to go straight up to bed as i knew it would be me getting up with my son, who was 2 at the time in the night.
DP followed me about 20 mins later, when he got into bed he started acting all stupid saying " i dont think you love me" etc and other shit like that. i was half asleep and was telling him to stop being so stupid.
then he kicked me in my back and i fell out of the bed, i got up and he punched me in my side and i thought he had cracked a rib, i was curled up on the floor thinking "what the hell is the matter with him" i got up and went to get into the bed again and he punched me, splitting my right eyebrow open and breaking my nose, the room was pitch black but i managed to crawl to the door, i must of been screaming because his dad and stepmum came running from thier room, i didnt realise how bad it must have been till i saw his stepmums face, and i noticed my blood splattered all up the wall.
his stepmum cleaned me up and was telling his dad to throw him out, i slept with his stepmum in her room and his dad kept him away from me in the other room.
the next morning i woke up to see him crouching next to me sobbing, he couldnt believe what he had done.
to cut a long story short, he apoligised profusly not being able to look at me as he was so ashamed of what he had done. he completly broke down when my son woke up and saw my face and was sick.
he swore nothing like this would ever happen again.
when we got back to where we live i booked an appointment with my gp to record it and also had to go to hospital for x-rays. i told him in no uncertain terms that if anything like this ever happened again, i would go straight to the police and have him arrested, he knows i will do it and he knows i would make it difficult for him to see our sons.
true to his word he has not even raised his voice to me, he is too aware that i gave him one chance and that would be his last chance.
i do not want my sons to grow up believing that it is acceptable behaviour to demean and intimidate women, i do however believe that because it happened in his dads house he is now aware that they will always be suspecting if he is doing it and i know how very ashamed he was, he idolises his dad and knows he let himself down badly in front of him.
before this incident he never abused me so i dont know why that one night he flipped out.
but i will say this, just because he has never done it again to me so far doesnt mean that i trust he could never do it again.
i really hope you can find a solution, im thinking of you...be strong xx
