Yeah , this will not improve. You discussed what you need on several occasions, and he can’t give it to you consistently.

It’s time to call it.

Be honest with yourself can you just be her friend , is so text her back and continue your friendship.

But if you’re thinking this is a way in to start dating her, just leave her alone.

Maybe it’s cause I’m autistic and have ADHD, but when someone tells me something about them i that’s seems important like their favorite color or food , or seven something I notice I try to make a note of it . Usually in the notes sections of their page of my phone contacts

I get you’re trying to help, but this isn’t something you want to get involved in.

There is no scenario where she doesn’t think you’re trying to sabotage her relationship to get her back.

If you’re concerned that she will be hurt, maybe give a heads up to one of her friends to be on the lookout, if he’s cheating they’ll find out.
