My exes mother messaged me...

This morning I woke up to a message from my exes mom and I have no idea how to respond. His mom is a nice person but I have absolutely no interest in seeing them at all. I don’t want to be rude though. If anyone could help me think of a way to respond I’d really appreciate it.

Her message:

“Just wanted you to know you are greatly missed!! I visited Jacob's dorm for a day and brought him back home for the weekend. He's doing great. You came up in conversation and we both want to see you again before too long. I think Jacob's too shy to ask as he doesn't want to upset your boyfriend. If you have time, give a jingle this weekend! XO I took this of him as we put things away in his room.”
