Should I ask?

So my BIL’s girlfriend is helping with the baby shower. Mostly the day of and the diaper cake which she volunteered for! She loves doing this stuff and she did our nursery.

Well BIL got back on the wagon and had a huge fight with her and us because we have her sanctuary. The next day things were ok and he was remorseful for what happened.

My shower is in less than 2 weeks and I want to ask if she’s still up for doing the diaper cake and helping. But i don’t wanna look like an ass or a pusher.

So should I give her more time or just ask? If so, how?
