Yes, I think if you want to slow things down you should say something. The worst that can happen is she will say no, she wants everything to continue as scheduled. You're considering letting that happen anyway.
But why accept defeat without trying? Marriage is about communication. If there's no communication, how can you hope to fix the marriage? The best thing I learned about saving my marriage was to spend time with my husband and talk to him. The mistake I made was to let silence grow in our marriage. Once we had that silence and coldness, there was almost no way to undo it. Breaking through the silence was the hardest part. If you have something to say, by all means say it. Say it thoughtfully and considerately, and with feeling. But not the ugly begging, crying, pleading, needy way. Say it will hope for the future and compassion for the past.
