Advice needed! This will be long 😔

My ex-husband and I have a beautiful 8 year old daughter together. He & I divorced (very amicably) when she was 3 years old.

Our custody agreement is 50/50. She is with me Tuesday - Thursday and every other Monday. She is with her dad Friday, Saturday, Sunday and every other Monday. I also turned down child support because I assumed as long as he's there for her physically I don't need him to be there financially.

He has always been a present father, a good father, and a great coparent to me. For 6 consecutive years - when our daughter turned 6 he announced (5 months into the pregnancy since they didn't want anyone to know, including our daughter) him and his girlfriend we're expecting. This only allowed our daughter 4 months to adjust to being a big sister, not being the only child anymore, realizing she now has to share her father after being an only child for 6 years. This was a HUGE adjustment and quite hard on her at first. (She's truly the best big sister). Her time with her dad dwindled down 2 twice a week. She was still receiving quality time with her dad during this time. Fast forward to 8months after her brother was born they then noticed they were pregnant again - this time with twins (how exciting truly! I always wanted twins hehe) He asked me to keep her on Saturdays and his mom will stay with her on Fridays, he will have her on Sundays until his twins turned 6 months old. The twins turned six months old at the end of August 2019. The schedule was supposed to go back to the original court-ordered schedule.. Well, that didn't happen.. he then decided to get a job for JUST Saturdays and Sundays (while she is suppose to be with him) THIRD SHIFT, therefore, sleeps his days away Saturdays and Sundays. He also now goes to school (I am happy he is making a positive life choice) Monday - Friday until 3:30pm. The text messages down below explain exactly what I'm dealing with. And I truly don't know what more to do or what more I can say for him to open up his eyes besides going back to court since he has not followed his court-ordered schedule.

Please give me your unbiased opinions! Ugh! Am I crazy for feeling this way? I want to continue having compassion for him, for his other kids, but not when it is affecting MY child negatively. Ugh!

(Gosh, I hope this post makes sense 😔 I'm one stress momma right now)
