First of all, it’s normal to feel disappointed in such a situation, there’s absolutely no one in such situation that wouldn’t feel disappointed, but this is one of the situations that tests your love for your partner. For me, if I tend to discover that my wife all of a sudden is a gambling addict, there’s absolutely nothing else I’d think of doing other than to assist and support her get over the addiction because I understand how addiction works and so I’d also understand that it wasn’t completely within her control and maybe things spiraled out of control.
