Review Detail of M_x_M in Trump card warm marriage

The story is quite simple so far... no major problem Easy to read... But there's something that baffles me is that... when the ML learned about the female being reborn into the body of his wife... he didn't even question the fact that she's not even his wife anymore... which means his wife is dead no matter how low the feelings between them might be... she was the wife he married!!! I mean he obviously had thought of making it work between them!!! So why he doesn't even care about her death... that's sorta heartless... which means he obviously didn't care... and in one way or another he was obviously the reason she was persecuted...
