Ex-husband Wants To See Child Less So He Can Have More Kids With His New Wife? What Are My Options For Custody?

A little backstory,

My ex husband and I were obviously married and divorced. We have joint custody but I am the primary custodian. We were great coparents until he met his current wife. I dont really understand what happened but he started being really disrespectful, argumentative, and just ridiculous for lack of a better word. Our daughter is 7 and he already doesn’t see her a lot. He should have her 1st, 3rd, and 5th weekends and pretty much spring break and summer break one major holiday a year but he frequently cancels. Cancels holidays last minute, breaks last minute, and his weekend visitations he cancels at least once a month. He is just IN MY OPINION kind of a crappy dad in general and my daughter has verbally expressed disinterest in going there and I want to make it clear she makes that observation all on her own. I do not speak negatively about my ex in front of her.

Now to today’s issue. He already cancelled visitation this weekend per usual but i got this text today after i just told him he needs to see his daughter more.

Text: “ Hey we are gonna take [daughter] for this holiday but after this we may not be taking her as often. We sat down and made our goals for this upcoming year and we decided we want to have children this year and in order to reverse the vasectomy it will cost 15 k. This means I will be working more and that it will require me to work weekends for myself and [new wife] Of course unless y’all wanna pitch in lol.”

What do i say? What would you do? At this point i want to relinquish his rights to her and let my current husband adopt her. Or full custody at the very least. I am sick and tired of his obvious disdain for our child but continuing to dangle her at his convenience.

Tldr: ex husband barely follows custody agreement and says he will need to see his daughter less in order to afford having more children with his new spouse. What should I say as I don’t agree? And do you think I have grounds for taking him back court to get full custody?
