I'm not going to invite a lifelong friend to my wedding
Why don't you want to invite them to your wedding?
I don't see any reasons, as long as you love someone you shouldn't be afraid of losing friends.
It's wrong to not invite your friends to important events in your life. They are your friend for a reason and might feel excluded if you leave them out.
We're living in different states, do you really expect me to invite them that far?
Even if they don't want to come because of the distance, I'm sure they would still appreciate an invitation.
