Not even married a year- hopeless?

[ForGump]

Before we got married, he was always telling me how marriage is forever, and then this is how he behaved during marriage. Is this the manipulative behavior of a liar?

Don't underestimate the ability of a person to be irrational.

It's possible he was scheming and calculating the whole time, but I think what's far more likely is that he is just being irrational. This could be a lifelong pattern, or something confined to his relationship with you. You probably have a sense.

So most likely, when he married you, it FELT to him like marriage is forever, and you were everything to him. But when it stopped feeling that way, he no longer believed in it.
