Should i say something....?

So 8 months ago my fiance and i moved out of CA to NV (only 3 hrs away). Well 2 weeks before the move my fiance and his step dad got into a big argument and long story short they're both too full of pride to admit they were wrong and his step dad still won't talk to us. His mom does randomly talk to us and has readded my social media pages.

She has been posting on my fb page (he doesn't have one) about how much she misses her son and wishes she could see him even ending the last post with " #guessimgoingtoreno ".

I'm planning a surprise party for tomorrow for his bday and invited them. She responded originally thanking me but when i addled if she thought she'd be coming for a food headcount she ignored the message (i can see that she read it). Then today she posted this

I really want to comment something like "coming to celebrate could bed extending an olive branch" or "are you coming to celebrate his 30th bday" but I'm not sure it's worth the drama.

Would you say something?
