Should i help future mother in law, or let it be?

A few months ago my FMIL was asking my FH all sorts of questions about the wedding planning and rehearsal dinner plans. He doesn't know much about the planning so I reached out to his mom and sent her a text letting her know I'd be more than happy to help her plan the rehearsal dinner, but I know it's usually (we're having a very traditional wedding..my parents are paying for it) the grooms family that plans it and I don't want to step on any toes and make it seem like I'm taking over. (I know the groom of a bride who did that. She totally, and purposefully, ran over all the ideas that the mother had. And made very last minute changes) So I told her that, gave her the dates, told her where we're going to rehearse (our venue has 3 weddings that weekend) and what time we'd probably be eating dinner. I also made it known that I had no problem keeping it simple since we're having a full reception with a meal for the wedding. Shortly after our engagement, they mentioned having a bbq rehearsal which I agreed would be great. I never got a response to that text. We've texted since, but not about that topic. My FH says she asks him about it from time to time. Should I ask her if she's made any plans, or leave it be? I've also tried really hard to include her in the planning process. It gets kind of awkward too because my parents are spending a sizable amount of money on the wedding, which she thinks is pretty ridiculous cause it's "just a wedding". She was there when I got my dress, and I invited her to the cake tasting and floral meetings, but she can only do weekends, which we all know is kind of impossible with weddings cause they kind of happen on weekends...
