I fondly believe that soul mates are a requirement from God. God made a soul mate for all of us and we have to find him or her and procreate.
There's nothing toxic about it except that if we don't find our soul maters we are total losers and deserve to feel unfulfilled, oh and if we find someone but he doesn't press the magic soul mate button, which we just know is being pressed when we find The One, then we should abandon that garbage bag in the name of God and search for that magical one who is promised to us.
What?
I'm not sure why women and men alike are all so confused about how this works. You grow up, get a job, find soul mate, have sex, have children, teach children to believe in God, children grow up, they find soul mates, have sex, and have children.
If you don't orgasm from vaginal penetrative sex it means he's not The One.
