Let's talk about trust bay-bee!
Being in a long-term & long distance relationship isn't always peaches and cream. There are many times when your trust is tested. Your mind even tricks you into believing things simply by thinking about them. You literally mind-F yourself.. you mindsterbate! Sorry.. let me continue....
If you do not trust your partner or if you believe what others whisper in your ear easily, then your long-distance relationship will not last and you'll be left with your made-up crazy thoughts. The best way to conquer this is by having constant communication. Instead of finding proof that your partner is cheating or trying to catch them in the act... consider thinking about all the great things he/she does for you. If there isn't anything there to find... maybe there really isn't anything there to find.... maybe. See it's that "maybe" that drives you crazy.
Some may argue that this is a very naive thinking. Think what you want and I'll think what I want ... Or, as the hubster would say "Why waste your energy by focusing on the negative... when you can focus and grow on the positive".
One of my FB friends recently questioned whether it was OK to look into your husband's email, belongings, etc. I was surprised by how many people said "Yes". So what if you live together, we all deserve our privacy and not because we have something to hide, simply because somethings really are just mine. I have no problem giving my hubster my email passwords, and leaving my journal out in the open but I trust that he will not violate my privacy behind my back. If you think your husband or wife is hiding something, then I suggest you re-evaluate your relationship and get to the root of the issue.
