Do you only try to attend weddings of those you have close relationships with or do you feel obligated to attend every one that you are invited to even if you have no relationship at all with the couple?
This is completely out of curiosity because you frequently read or hear people say “(friend’s brother’s whoever) invited us and we are expected to attend but we aren’t close to them”. Isn’t that what the decline option is on the rsvp? Because it is not a summons and no one has a right to make you guilty if you don’t attend.
