Anniversaries don’t exist unless you’re a total bitch and completely crumble during a DTR. For real though, when one of your buddies’ girlfriend is outwardly celebrating the 1 month, 3 month, 6 month, 1 year anniversary, call his bitch ass out on it. Be merciless, it’s for his own good. The first sign you’re in a bad relationship is the 1 month anniversary celebration. It shows you’re completely at her mercy, don’t let it happen to you.
Besides, if you’re playing it right she should be hesitant to celebrate an anniversary outwardly because it will just shove a reminder into your face of how long you’ve been together. Presumably this will make her afraid that this will cause you to break up with her. Ideally, the anniversary goes relatively unnoticed with the only sign of it being a subtle hinting at it on the girl’s part.
Remember, she doesn’t like you, she likes “us” (her and you), so an anniversary is a big deal. And, obviously, holidays aren’t anything but anniversaries shared between couples. So on both counts, it’s best to brush them off professionally like the shit tests they are. And if you can’t pass those shit tests, it’s time to take it back to the mattresses.
