It is important to be on the same page with your partner on the definition of unfaithfulness. Confront any inconsistencies before you find yourself in hot water.

This is a conversation that definitely needs to happen between you and your partner, and it’s best if it happens before this becomes an issue. Different people have very different ideas of what constitutes cheating and what is completely harmless.

Drawing Lines
Some people believe that flirting with other people is over the line, while others believe that as long as you keep your pants on, all’s fair. These differences in attitudes towards faithful behaviour can often turn any love into full scale relationship war, so it’s best to draw lines with your partner near the beginning of a relationship and clearly determine what is fair game and what is foul play. Lines concerning ex’s are among the most important to establish because some people will only feel comfortable if their partner is completely avoiding their ex, while others feel it is alright to stay friends. And some people feel that if a friend has had a few too many, the responsible thing to do is to have them stay over. Which may all make sense to one person, while another only sees that his girlfriend’s ex just spent the night at her place and the relationship may be over. Lines are important and agreement over lines is absolutely essential to a relationship that works.
