I wouldn't put too much creedence in what your STBX is saying. He is looking for his best intrests. Could it be he is trying (unconciously or otherwise) to get you to doubt yourself. If you feel youneed to see a therapist, then go. Find childcare through family, friends, church, or some other source than your STBX. You would need to do this if you had a medical doctor's appointment... this is no different. You cannot force the other parent to utilize his/her parenting time.

I would avoid boo hoo time while the child is around... if she is younger, then wait until she's in bed or down for a nap... if she's older have mini sessions in the bathroom if you cannot hold off until she is in bed. And if she does see you crying... oh well, it happens.... just tell her you're sad and that you need a hug. If she is older and understands what is going on, she may need this to feel it is okay to be sad too. So basically don't take his words to heart and make arraingements to do what you need to do.... even if he won't help.
