Husband has form for lying. Big things and trivial things. Has to date lied about a number of big things, mostly to do with big purchases when we're skint. A laptop and a car are examples of this, along with repeatedly lying about doing therapy when he hasn't.
Today a new tablet appeared. Asked him how much, and he said £100. Great I said, maybe I can get one too. Cue him getting all angry at me because I "obviously don't believe him". At which point I say that actually I don't believe him as he often gets angry and defensive when caught out in a lie. I ask him to show me proof if he is telling the truth, and he says no, because, and I quote, "I've ruined his enjoyment of his new tablet now".
My question, am I being unreasonable to distrust him, or not?
