Reply To: He broke up and I don't understand why? Guys, can you explain this behavior?

I don’t know him or his rabbi but just being a rav does not necessarily imbue with special abilities or insights. I can tell you from experience that some people just need someone to decide things for them because they don’t want to be responsible for their decision. The rav apparently based his advice only on what the guy told him, which maybe accurate or skewed. As a person who got married older (mid 30s), I recalled once asking my rav advice whether to continue, and rather than decide for me, he guided me, and I made my own decision.
