Pretty much as it says. LTR of 1.5 years will occasionally make a joke about me cheating. It's not as if she doesn't believe in my ability to do so either, she's approached me about concerns with other girls before.

A simple thing such as me finding an earring in my bed and asking if its hers, she will turn to: "Not mine, caught you now!" Is this a sign of Insecurity? Shit Test? Comfort Test? I usually reply with a "whoops, gotta be more careful?" + shit eating grin.
