is time linear or branched?

if you travel back in time to change something, then the reason for the time travel wouldnt exist, so for time travel to be possible branched theory must be true

well the variety that i have pushed through were couples who would want to split up due to changes or "problems" that may occur during a married relationship

i had specifically targeted couples who had or are going to be married

now if youd like to calculate how many happy couples there are a this specific moment that would be high in variables and less likely to be an accurate account

isn't species defined through their genomes?
so until all of them are different wouldn't that qualify as new species?

if you want to talk psychology yes these statistics are very disputable, but if you are looking for singular linear progression through the train of an average person's life time, these statistics prove true for at least americans

so the reword what i was saying i guess you could say no happy but together with less problems?

real math:
to be socially acceptable couple
take the males age divide it by 2 and add 7 that is the minimum the female's age can be

but remember the statistics of a happily married couple turns out to be around 1.2-1.4%
average americans go through 8 relationships before marriage
1/8 = 12.5%
of those married the divorce rate has increased to 60%
statistic drops to 5%
of those after calculating overlapping causes
how many of those are in counseling/cant afford divorce/together because of children

statistics of a happily married couple 1.2-1.4%

just want to know what first impressions i give off
my pics are me normal, or me intoxicated, you can decide which of the two

but im a real business man 9-5

so i welcome your opinions :)
