A boyfriend who enters into several relationships at the same time is often called as a “cheating boyfriend”. A cheating boyfriend is infidel and may have several flings at the same time when he is a part of a rock-solid or steady relationship already. Guys who are typical playboy types can fall for multiple girls at the same time and even enter into a relationship with more than one girl simultaneously. Nightmare happens for the guy when he is caught red-handed by one of his several girlfriends to whom he has made a commitment. Infidelity by any partner in a relationship causes great pain to the loyal partner who was extremely committed and serious about the relationship. So girls should always stay alert that they chose a loyal and trustworthy partner who does not bluff them anyway. According to Caprice Bourret, “You could be going to have supper with someone who happens to be male, and all of a sudden he is your boyfriend of nine months... and I am cheating on my existing boyfriend.”
