My Inadvertently Abusive Husband

What am I gonna do about this?? Really...!?!? Lately I have sustained bruises to my chin/jaw, nose, thigh, back of my head, butt, etc. People this is no exaggeration. The chin/jaw was at work when I needed some help taping a paint roller onto an extendable rod. I held the two together while Ben wrapped duck tape around....just as a lady with a baby & cat was walking by, the tape had a cut in the edge and snapped when Ben was holding it taught. His fist met my jaw with a loud popping noise while I was mid-sentance saying hello to the woman. He really hit me hard....I was stunned and my 'temper' instantly fired up.....as Ben wouldn't stop hovering and kissing me...telling me how sorry he was in between uncontrollable bursts of laughter. I just walked away with all the attitude I could muster and got back up on my painting ladder. I am not angry person.....but when I am spontaneously bopped in the face ....I am not a happy camper. It wasn't long until I was laughing hysterically.
Incident #2: Ben drops me on my head onto the cement floor. I was somehow pushed off our bed during a 'wrestling match' and he was holding my arms and pushing my body off with his legs.....then let go...and 'thwump'...thats pretty much it...I don't know how else to explain it.
Incident#3 Never dare Ben to a towel-whipping match....you will pay.....with purple thighs.
Incident#4 Ben was taking off his sweatshirt and as it was stuck over his head....I took the opportunity to poke him in the belly. It was like setting off a mouse-trap and his cat-like reflexes caused him to unintentionally punch me in the nose.
Incident#5 This one he totally did on purpose....but I am not sure he thought he would hurt me. We were having a crazy night play-fighting (I should learn...I always lose except for when I accidently jab him in the eye) and he decides to pull me up a flight of stairs by the legs of my jeans......It was hilarious at the time...but my bum told me later that it wasn't a great idea.
Thats all I can think of at the moment....but maybe thats the brain damage kicking in...
I am think of asking for a full set of football padding for Christmas.....especially a helmet for everyday use. Its not a bad idea I'd say....
