see and talk to each other daily, holding hands, cuddling, frequent text messages and phone conversations, jealousy of a member of the opposite sex (levels of jealousy different in degrees of psychosis of the individual), constant denial of "anything going on" and constant reminders that "we are just friends." There are also various levels of physical interaction that occur that range from kissing all the way to intercourse. If you or another are suffering from any or all of these symptoms, you may be involved in an off-brand relationship and may be in dire need of making it official or officially ending it;however, this would result in an off-brand breakup (see off-brand break up for more detail).
you may know of someone in an off-brand relationship, it happens all over the world. It may be happening to you! my suggestion, label it or end it. (see off-brand breakup for more details)
