What ever you decide Ellie, re the probable phone call, decide firmly.
If a kid accidently passes the phone, say the preplanned words and hang up. Don't wait for a response. No conversation. And remind yourself to just forget it and not let it get to you at all. No response or reaction-predecided.
If you can avoid speaking to them at all, that would be great. What ever happens, just enjoy your day and your bike and your new attitude to not let them upset you, especially on your birthday.
Also, your hubby offering you a chance for a birthday party may have been his way of wanting to give you what you gave him. Maybe next year, you can have a list of who to invite, what he could bar-b-que for you, and what beverages he could have on ice. You deserve to celebrate with the best of them Ellie! Take a rain cheque.
