Many men tend to get into relationships for sex and when the relationship fails to induce emotional attachment over the time, men get bored.

Now this one is bit complicated because men seek simpler things in life like sex, food and companionship. While women are driven emotionally and materialistically.
But for men, sex is a trophy and for women, it is more often a means to an end (payment, no offense intended). Basically for men, it is what they get and for women, it is what they give in a relationship.
Men have difficulty in understanding the concept of love and lust seems to be the closest to it. Those who have such concept of love, it means, they are not ready and as the responsibilities grow, they’ll seek another relationship which often leads to cheating.
