I DONT WANT KIDS WITH MY HUSBAND ANYMORE

Idk if im over exaggerating, but i left the house, came back in and seen my kitten laying on the floor... my husband spit on her, she was bleeding from her mouth and eyes a little and she isnt breathing right so im at the vet... over some fucking headphones!!! This was a wake up call that i shouldnt have kids with him because if he would do that to a kitten over bitten headphones, i can only imagine how he would do a child... this marriage has been in the dumps since i married him and onoy reasoj why i stay is because he dnt cheat... but now, i see its because he has a very bad temper problem... im 24 and feel like i wasted 5 years of my life thinking this union was good... im actually scared of him now.
