I don't know what to do here and need some advice. There's a girl who I worked with before, and whose family used to be good friends with my family, but my grandmother and her mother had a little falling out and have not spoken since. Anyway this girl invited me to her wedding, which was... 5 years ago, and to her baby shower like 6 months ago even though I hadn't talked to her at all in almost 2 years. She was never like a good friend of mine, and she's not on my invite list. Today she sends me a text message saying "Just wanted to say hello and see how you're doing? I heard you're getting married and was wondering if you had a registry?" This makes me feel akward. I told my mom and my mom says "You should send her an invitation!" I don't even have her address, and to ask for her address now... that doesn't seem right (and I don't know anyone else who would have her current address). What would you do?
