He has a girlfriend. And that girlfriend is not you.
There are certain things that we don’t really question in life: red light means stop, Coachella is hella overrated, One Direction fans are bat shit mental and so on. But for some reason, when we really like someone, we question the shit out of their relationship status, even when it’s right there out in the open. Social media doesn’t lie; Man of your dreams is IN A RELATIONSHIP with some stupid girl who doesn’t even look THAT pretty in her profile picture…
Bottom line: sitting around, pining and day dreaming of the day he confesses that his girlfriend is in fact some sort of cover up story because he’s in witness protection and you are the one he truly loves (or just that he dumped his girlfriend and wants to be with you) is not going to do you any favours. Best case scenario? His relationship crashes and burns, enough time passes so that you are not his rebound, and something beautiful kindles between you two. Worst case scenario? You murder the girlfriend and are sentenced to life imprisonment. Most likely scenario: you are going feel lonely and binge on Netflix, turn down opportunities with people who are actually available, and drive your friends nuts with how often you analyse his text messages.
Do your best to limit your time around him and maybe think about hiding his activity from your newsfeed. Nobody wants to see their dumb trip to even dumber Paris…Fear not, with time, feelings will fade if you do your best to not feed into the fantasy. But seriously, it just sucks. It sucks a big one. Always be cautious around the handsome boy with the clever jokes when he already has someone to hold.
