There ya go.. YOU have freedom that he doesn't have.. how ironic eh?
The thing is, there are lots of things people can do to give them a short term thril. Some of these are healthy
Roller Coaster Horror Movie Horseback Ride
some aren't...
Drinking Crime Vadalism (ya I know its a crime, but its often portrayed as "art".. it has a similar dilmena that infidelity does) Fistfight (if you win) Practical jokes Bullying people
Both the healthy and the unhealthy give you a RUSH of excitement... and it DOES produce some happy feelings chemically speaking.
The DIFFERENCE is the long term damage that is done by the second group.
They BOTH produce similar FEELINGS, but the second group does DAMAGE.
Chemically in the brain, the results are quite similar and to the casual observer in both cases the person will appear "happy"
But, the second case dismisses the long term happy. The difference is like comparing a mutual fund investment to a roll of the dice at a luxury Las Vegas Casino
These people just see the short term feelings he's getting and think "its all good then"...
He IS enjoying himself, but its a hollow enjoyment that he will one day grow to regret.
One day twenty or so years from now he's going to have to look his children in the eyes and explain to them what a horrible thing he's been doing for the last three months... and he will NOT be able to run AWAY from that...
He's done that damage now and he WILL have to answer to it some day.. He just isn't aware of it yet.
You have no need to text him, you have what's most important to you now, your children and your life ahead of you... HIS is on a road to somewhere you do NOT want to be part of ... so steer clear..
