I honestly believe we are still part animal, even though we are human beings we can sense things. Im not a jealous person either, some would even say I'm pretty relaxed when it comes to relationships, but that's just because I don't feel threatened by anybody, I mean it's not like I own somebody and it's being stolen. On the other hand the very few times I have felt jealous or felt the person I'm dating is getting with someone else, HAS BEEN THE CASE. Not everybody is going to get on board for this sixth sense stuff but it has worked for me so far.
