5. They Never Show Affection In Public
I don’t necessarily believe in the mantra of “once a cheater, always a cheater,” but I do believe that anyone who cheats with you will cheat on you. If you know for a fact that your relationship with your new guy or girl didn’t have an honest beginning, there’s no reason for you to think that you’re the Special One that will finally convince your partner to be faithful til the end. If they hid their relationship status from you before you became an item, that’s just a bonus sign to convince you to nope the hell out of there.
Nobody is asking you to force your tongue down anyone else’s throat to make you prove your loyalty. That said, if your partner straight-up refuses to hold your hand, give you a peck on the cheek, or do anything else that would reveal to the world that you’re something other than best buds, there could be a very sinister reason why. Maybe they’re afraid you’ll run into one of their old flames, or maybe they want to see exactly how many strangers would want to bang them if they appeared single, but neither option is very good from where you stand.
6. They Act Differently With You Around Certain Friends
They might be all lovey-dovey with you when you’re alone, but if you notice their behavior changes when they’re around their friends of the opposite sex (or worse, one friend in particular), it’s probably because they want to appear like they’re at least a little bit available.
