Starting to get frustrated! My husband hasn't slept in the same bed as me for at least 3 months. He blames it on me nursing which I know is a lie cause she will only be two months in a few days. He makes big decisions without consulting me. He just decided today to sell my car (the only car we have). Like who does that?!? I honestly think I would be better off alone.
