TTC - Married vs. Not Married Responses

Do you respond differently to women asking about trying to conceive if they mention they're just have a boyfriend? Why?

I've noticed that I give the same information regardless but I give it in a nicer way to married women. Trust me, now that I've noticed it, I'm definitely going to change. I don't even fully understand why.

I hope I don't get bashed because of this. I hope it makes some of you reflect on the manner in which you give advice/information.
