Oh my goodness. Things sure can flip direction really quick.
I’d not talk to W’s mother. Blood is thicker than water, and in the end she will likely defend and support her daughter.
Talk to your Mom and Dad. Call them. Not text. A call. Person to person.
I’m not sure how much they know what is, and has been going on, so be prepared to explain stuff. You don’t need to go into all the dirty details, however they are getting dragged into this from W, so best to ensure they have a more clear picture. They are probably rather worried, I’d suspect.
If W or things are really getting out of hand, call the authorities.
When things cool off, correct the credit card mess.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
