Struggling with coparenting

UPDATE: She has been admitted to the hospital. Her dad showed up for 20 minutes, when I texted him and asked if he could come back in the evening for a few hours so I could have a break he basically said “I’m coming to stop by, not stay” so my boyfriend came to hang out with her and I, and gave me a ride to go shower.

I am struggling to not crash out on him and get angry.

Hello all. I am struggling with co-parenting - as the title states- my ex husband refuses to do anything for our daughter when she is sick. Which due to her asthma, has been most of this winter. He blames me stating he doesn’t want to be around me, which I get I don’t want to be around him! However, our daughter has gone to the hospital multiple times, he has turned off his phone, refused to answer, not shown up, won’t take her for visitation time while she’s sick, and all the while says it’s my fault he doesn’t. Recently she has been diagnosed with RSV and her doctor thinks within the next few days we’ll be admitting her to the hospital.

I love my child more than anything, but having some help from her dad would be nice, just come to the doctors, or take her himself! Help with administering medications, and breathing treatments.

All of the high conflict started when he got a new girlfriend, who ironically, doesn’t want kids.

I don’t know what to do and any advice will help.

I know I cannot make him a good father, but I so desperately want my baby to have a dad like I have. Willing to move mountains to make sure she’s ok.
