Party coming up. X girlfriend will be there
A female friend is having a party. She requested my presence, but she is good friends with my x. I told her I would go then finally realizing my x would be there. I don't want to associate with my x because of her I believe cheating on me. We have been in no contact 2 months.
Should I
A) tell friend I cannot attend without a reason
B) tell friend I cannot attend with a made up answer (so I don't show weakness to the X that may get back to X, or friend just assumes I had something come up)
C) tell friend I don't want to deal with the x (showing a weakness which may get back to the X)
D) just go and man up
Thanks
