Request for some love and strength

(Sorry for the long post) This is for my best friend, my sister from another mister, she's not blood but she's been such a huge part of my life since highschool.

She is a single mother, 4 gorgeous babies that I call my caramel babies, she is beautiful and strong and an absolute queen but she can't see her own crown. Both her baby daddies were abusive and just scum of the Earth and have tried to knock the crown from her head so many times she doesn't see her worth at all.

She's been sort of trying to get back in the dating game, I know she wants that deep meaningful connection and consistency that marks a real uplifting wholesome relationship, after the dark mess she's crawled from. (She was in these abusive relationships for a total of 9 years or so). Both her baby daddies have found new women, and she is just having a really hard time and feeling so down that she hasn't found anyone yet.

I have her for a girl's day and I've tried to talk and tell her not to measure her worth by what anyone else has done, that she's an amazing person and someone will see that, but also that she doesn't need another person to be the Queen she is. But, I have never been in a situation like hers. I have a little girl but with a man who has always treated me amazingly, I've not had to try to date with kids, (and honestly, most guys/girls seem to run from a woman with 4 kids). So, I was hoping maybe some of the queens (or kings even) on here would share some wisdom or love that I can then show her or relay to her.
