Why would a man do this?

My fiance cheated on me for a year while he is in another counrty.. he confess it and we brokeup but stay in contact

he told me that she is a sick crazy woman and he will left her anyway and he is unhappy with her

After two years our matual friend sent me photos of them still together.. he goes on vacations with her and they live together

I sent those pictures to him

And he replayed with the same words..

Why would he do that?
