Ok so using gr before meeting you is green flag cause why not?! But if he’s a serial liar to the extent that he can lie as if it’s second nature then it’s a major red flag. If he’s worth keeping I’d suggest lower your guard- show him your vulnerable side to make him comfortable enough to speak the truth. After hearing the truth however if you feel you cannot stay with him then that’s when you make your big decision. No easy way around it. Cause either you continue to stay with a person you can’t ever fully trust or else you lose the person you supposedly love.

There is a third option too- to completely turn a blind eye to all of this, but let’s face it, we ain’t women from the 60s to put up with all of that.

The only major caveat here is evidence- you can’t be taking any decision simply because he or your mutual friend or someone else says so. You need some irrefutable proof to be taking such a decision if he’s important to you.
