why do men or women cheat?
It's human nature I believe. The grass is always greener.. people get bored. Too comfortable. Too lazy. Don't want to try hard enough.
A relationship is a commitment for BOTH people. If someone doesn't want the commitment, avoid it. Otherwise they're wasting their time and their partner's time. A relationship also takes a lot of work, from BOTH people. To make anything work you need effort.
Bottom line, if you want a relationship, just be smart about it and have common sense. If you suspect your partner is cheating, ask yourself why first and get some facts first. Nothing worse than being accused of cheating when you're been 100% faithful to your partner. In my experience, if your partner accuses you of cheating, it's their way of lashing out their insecurity because they are the ones cheating on you. They're redirecting the blame. Some people are awful.. but I've always felt that if you are a good person, you'll attract good people.
