Also, if you are there with someone else it will look more obvious that you are not there with your wife. It may make you feel more uncomfortable ultimately. At least you can deflect any awkward questions with your school response if you are alone. Of course if you can't face it, you don't have to go but I think it would be nice for you if you could. Weekends can be very long...
If you go with your wife, make it look like you are perfectly capable on your own. You will seem more attractive to her that way. Make her notice you instead of just being there.
