Sincere responses only please?

A very close friend of mine told me that after 4 years his estranged wife got in contact with him under unusual cirstances (she's incarcerated) and she wants them to rekindle their marriage at the moment he is somewhat involved with another lady and he asked me what do I think of his situation I honestly don't know what to tell him I asked him do he still love her he said that he will always love her but he is no longer in love with her and he don't know what to do. Any suggestions??
