FY, Go ahead to the class. If she should ask, you can tell her about the meetup group and how you are making new friends, etc. After all, she goes out w/her friends and leaves you to do your own thing. This might make her a bit curious about you and your whereabouts at some point.
I think you and your w will enjoy visiting w/her family. Dinner sounds like it will be fun. This gives both of you something to look forward to.
Hang in there!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
