<human>: My family and I don't know what to do. She isn't a bad person, but she is making ultra shitty decisions.

She has a little boy(Age 6) and a little girl(Age 4) (my God daughter, actually). They're both pretty good kids and have had a rough time, especially due to their father passing pretty suddenly a few years ago. The mother doesn't take good care of the kids. Their clothes are too small, their home is a mess, and they have pretty obvious learning and developmental shortfalls.

My family and I don't know what to do. Out of the blue she married this guy who, on social media, is seen throwing up gang signs. We've never met him and they must've gotten married at the courthouse or whatever. Everyone found out on social media. Now she may be pregnant... again.

I don't know if she works. I think that she quit her job relatively recently. She's my cousin and I care about her, but I care moreso (as does my family) about her kids. They've been through enough. Now my cousin wants to move them from their home (about 30 minutes), and move even further thereafter (hours away).

Does anyone have any advice?

Can you summarize the given text in a few sentences?
<bot>: Cousin who has 2 kids with a dead guy randomly got married to a potential gang member, feel bad for kids.
