I don't know. Everyone leaves a relationship for different reasons.
Take it v slow. It's dicey...could be they were ready to leave previous relationship way before they did...its what many do...then it might be ok.
And...of course you note how often someone mentions 'their past affair'...and if they never mention anything that could be good but they could also be v self-aware to not do that...lots to consider.
KInd of fits te definition.
Always the optimist:)
Im not judging, jd. Im jealously appreciating:)
Depends who ended it. The person who ended it was usually "out of the relationship" a long time ago.
