The easiest way to know if your partner is cheating on you is you. It's funny but it's you.
When you start having that natural feeling that something isn't right. Don't just let it slide, discover the reasons for such feelings
Cheating partners are use to telling lies. They don't keep ther mobile phones far from your reach and are mostly with their mobile any where they are going.
A cheating partner will also reduce the time he/she spends with you complaining there is no time.
Hmmmm... You must have had such experience of someone cheating on you
