I know exactly what that's like from the other side. My husband can be fake, he tolerates things that I would never tolerate, espeacially from people at work.
I've seen my husband get very burned out, and he drinks to deal with it. I think suppressing all these other emotions are unhealthy, and it could lead to larger problems.
I highly doubt your fake, it sounds as though your just trying to be a decient person. Everybody wants to be decient, but sometimes being real could hurt another person, but it's neccesary at times.
Hope you feel better.
