I hope so.
Honestly she's doing well to be in her mid-20s without a kid. It is a big thing to break that cycle of having OOW kids and having them at an early age. She seems mindful of not having kids right now, if nothing else.
@Crackers Phinn Pat yourself on the back for that. I'm sure having you in her ear helped to prevent it.
Now you gotta get her to leave her mama and live on her own. Keep working on her and get her ready for the next matchmaking session. I do think that you should try it again, give her another chance.
Tell her to keep her mama out of her own finances and her next SO's finances too. Mama should never get a whiff of the his true finances (especially if he has a high income potential) and stay out of their business period.
ETA: Could you set her up with a mentor? An older black lady who can teach her some things? She probably needs to hear them from someone outside of the family.
