People believe different things about twin flames, and I respect that - but I don’t agree with it.
Personally, I think anyone who thinks you can have more than one twin flame hasn’t met their twin flame.
You can have multiple soul contracts and soul contracts with more than one person. But there’s a reason why every twin flame I personally know who is with the real thing knows there’s nobody else quite like their counterpart.
Anyone who thinks they have multiple is probably dealing with multiple soulmates at best. Or it’s wishful thinking and they’re dealing with people they just have a crush on. Something they probably need to work on before they’re ready to meet their twin (if they have one).
Multiple soul contracts, like multiple soulmates or karmics? Sure.
