A few months ago, the same thing happened to me. I was already at the party and my boyfriend texted me saying he'd get there after it stopped raining.

Only it kept raining and he stopped replying.

Me being an absolute lunatic, jump into a panic mode and think he got into a car crash or something similar. I keep texting, calling, texting and calling his friends but no one knew where he was.

A little after midnight two of his friends offer to go to the party to keep me company and stop me from having an anxiety attack. It was an exclusive event at the museum I work with, so they arrive with their suits, ties and tidy hair, but by the time they got there, my boss had already broken out the tequila shots and expensive whiskey. Needless to say, there were more than a few naked historians running around the building.

After the initial shock, we all have a blast and end the day watching the sunrise from someone's apartment (neither of us have any idea who that person was, only that they were filthy rich and was sober enough to drive us there). I charge my phone there and see my boyfriend calling me, he apologized and said he was sleeping, his friends make fun of me for being a crazy obsessive girlfriend and that was that.

After that, we share an uber and I pass out at home.

Later in the day, my boyfriend sees the instagram story one of his friends posted and he's lowkey upset. The party was pretty wild and it was pretty much a once in a lifetime thing.

He had a serious case of 'fear of missing out' and we had to refrain ourselves from sharing any possible inner joke around him, but keep in mind, although he missed the most epic party of the year, he never once attempted to blame us for having fun without him. Never.

While I do think you should give her some time to cool off, do not let her pin the blame on you.
