Tired of yelling, fighting, and ignoring a mate, a person might choose to take a temporary break from all the madness. However, this doesn't mean that a dead-end relationship is suddenly headed somewhere. Some couples deceive themselves into staying long past the expiration date just because they had a short-term honeymoon period.
If he was ugly a month ago, chances are he is still that ugly guy just taking a break from acting ugly. If she had been treating her guy wrongly for a long time, a couple of weeks of being nice to him doesn't mean that things are getting better, especially when she is still talking badly about the guy behind his back.
Temporal happiness is deceitful. It makes you falsely believe that someone, who isn't good for you, just might be okay for you. However, the truth has a way of showing back up to remind the wishful thinker, the gullible, and the crazy in love, that there is nothing to what you call a relationship, but smoke and mirrors.
