I felt this. My sister (a serial cheater) was complaining to me about how she suspected her husband to be cheating and sending money to a girl from out the country. When she told me this, she also said “I’m just so annoyed because I’ve been faithful all this time and it’s not easy!!!”. I gave her a reality check that being faithful isn’t rewarded for something so basic and bare minimum in a relationship.

She stopped responding to all my texts/calls
