Phillip and i had it out last night

last night hubby and i had our first real fight, and boy was it a bad one. he never backs me up with it comes to DD and i finally had it. My MIL gave my freaking 2month old a bite of ice cream!!!! are you freaking kidding me. every time i say anything to him about dd he tells me "she's fine!" ugh it gets so frustrating, and i have been holding it in for so long that i couldn't take it anymore and i blew up! he told me that he never realized that he didn't back me up so much. And i felt so bad about the whole fight and that i blew up, but we ended up talking it out, we both apologized and he actually cried (but shhhh don't tell him that i said that!)
