There are few things quite as heartbreaking (not to mention mortifying) as finding out that your boyfriend actually had you as a side piece. Sadly, a lot of guys aren’t honest about their relationship status, and it often falls on us to figure out whether they’re full of crap. If the guy you’re seeing is doing any of the following, it’s a sign he’s most likely lying about being single:

HE REALLY MAKES A POINT OF SAYING THAT HE’S “NOT INTO THE WHOLE RELATIONSHIP THING.” This is just a bad sign, regardless of whether he’s telling the truth about his singledom. When a guy says he’s single but just looking for a fling, there’s a pretty decent chance that he’s not as single as he says he is. After all, why wouldn’t he want to date you?
2. HE ONLY INVITES YOU TO HIS HOUSE, OR TO A HOTEL ROOM. If a man seems to be going out of his way to keep the two of you out of the public eye, it’s most likely because he’s worried about being caught by his girlfriend’s/wife’s friends while he’s out with you. The more he flaunts you, the less likely it is that you’re his side piece.
