I've been on both sides of the fence being cheated on and being with women who are married/boyfriend etc, It's just science and chemistry, womens pussies burn so hot sometimes and their hormones rage to the point it takes over their moral judgement and instincts, any woman that is remotely attractive has a swarm of men trying to get it desperately plotting and scheming to make it happen all it takes is time and pressure. This is why men aren't meant to "settle down" with one woman, I just don't believe mother nature intended for it to be that way, if it was if love was a real thing like in the movies and songs human beings would have gone extinct a long time ago, it's survival of the fucking fittest in this world, that's the reality.
