How many of you are still friends with your ex?

It's been a year since we separated. She had an affair with her coworker. I invested heavily into making it work (not financially)

She still chose affair partner but wants to maintain friendship.

I feel like it is her having her cake and eating it too.

Maybe over the years we can be friends again but how do I be friends with someone who caused so much pain?

We have kids, which complicates all of it. I know they want us to be together.

How are you guys maintaining a friendship if you are?

I’m a 30M with a 3-year-old daughter. Her mother and I broke up two years ago, and I’ve spent the last three years sacrificing career opportunities to be flexible with childcare, daycare pickups, and day-to-day parenting.
The problem is that her mother refuses to share her work schedule consistently, so I sometimes don’t know when I’ll have my daughter until the night before. This has made it difficult to plan my life and focus on my career.
After dealing with this for over a year, I told her I’d pursue a court-ordered parenting schedule if we couldn’t establish consistency.
I’m hesitant because, as a Black father, I worry about being treated unfairly in court, and I don’t want to create more conflict that affects my daughter.
Has anyone been through something similar? Was going to court worth it? I just want consistency, stability, and the ability to be a good father while building my career.
