Dating a married man who loves his wife
A man in grief, angry, unhinged, or feeling newly free of cumulative stress can be a vulnerable target for an outside person, or even an unthinking seeker of temporary escape.
As those problem must eventually re-emerge, the subsequent breakups are likely to happen more quickly.
A newly separated partner is often searching for validation and support and cannot see beyond those needs.
If, on the other hand, a couple has been separated for quite a while, have made multiple attempts to reconnect and failed, the partners may have come to the conclusion that divorce is inevitable.
A partner who may have understood a one-night stand that is immediately confessed is less likely to feel as humiliated as one who finds out much later or when a relationship is more established.
She will likely assume that person was there from the beginning and the reason for the break-up if her partner asked for the separation.
