ugh im so done! im so frustrated and cant anymore! my sons been sick for the past few days with an ear infection and his dad thinks its okay to cuss at me while im giving him medicine because he starts crying...i take care of our 99.9% of the time but when I'm not doing what you would do im the bad person! its getting to the point where i can't stand being him because hes constantly questioning my parenting skills...youre a freaking 30 yo man who has no clue what to do...but i cant parent in your opinion.
