Well would you ? this thread may or may not have been inspired by true life events. All similarities to real people are entirely coincidental ...
I would treat this as any new relationship with history.
The same as starting dating a friend or a foe or the writer of Robinson Crusoe. That is assuming there are no "unresolved" issues.
If there is a passive in the relationship (unresolved issues), they would need to be resolved before entering a relationship, the same as entering a relationship with a recently divorced christian brother.
