based on what i understand, in my opinion of course...

*Does everyone have a twin flame?
only those who have ascended in the past and returned to earth are split into two. those yet to have ascended do not have a twin as they have not been split in half

*Do twin flames meet in every lifetime?
they will not meet in the physical if polarities have not been balanced and emotional memories from the soul have not been transmuted

* Is it possible for neither to be aware that they are twin flames, but have a "drawing" to one another?
yes, as spirit can allow one or both twins to feel their energy from people/interfaces who are not their twin. like a decoy with the primary purpose to flush out darkness. it would also be possible for spirit to withhold the energy leaving one or both unaware. it is also possible that after having encountered one or more decoys the twin(s) may be skeptical if it's the real deal

* If you are married to someone other than a twin flame when you realize you have a twin flame what are you to do?
get drunk

*If you think someone is your twin flame, but you are not sure that they know this or not, how do you deal with it?
be patient, have faith and trust that the will of spirit will be fulfilled. having said that anything is possible so anything goes

*If twin flames get together in the physical how do they transcend/ or connect together in the spiritual?
prior to meeting in the physical their spirit is already merged/one

* do people with twin flames also have soul mates?
yes, soul mates are simply people we planned to meet prior to birth. the exchange is not limited to sexual/platonic relationships, could be literally anything
