Ok i need some input. Ok so about seven weeks my daughter got ahold of tyenol that i didnt put up. I had a hairbrain moment i normally dont do that. Well we went to the er by ambulance and spent five hours there thankfully she didnt get any in her system. I cried the whole day. Well an officer called cps on me. And ive been dealing with them on my own. My other half has been avoiding the situation hes been involved maybe twice this whole time. When i ask him if he thinks its my fault he says no but his actions are telling me something entirely different. What should i do? I cant confront him with a child around and hes a brick wall to talk too. Im overwhelmed and confused about his feelings on the whole situation.
