Tired of fighting

Mo
I need some encouragement if any ladies can relate. My ex husband and I share placement of our 6 year old daughter. He texted me last week the he wants to move our daughter to a cheaper daycare because it's too expensive for him and his wife. Last night when I got to his home to pick her up he asked me in person. I told him I do not agree to move her it's not in her best interest because she just started Kindergarten and she has been in this daycare over a year. She has friends there and knows the routine. He threatened me to court and said he didn't need my permission to move her. Our court paperwork states we both have to agree to move her. I am just so tired of fighting. I will for our daughter's best interest, but every year if things don't go his way or what he wants he finds a reason to harass me. Normally, I deal with it. However, being pregnant has made my hormones and stress shoot through the roof. Any advice would be appreciated.
