A lack of trust which is the foundation for a relationship, there's also bad timing, you meet the right person at the wrong time, which sucks.

Im going to sound crazy here, but I honestly think we are not meant to be married or in relationships. If we were there wouldn't be such things as divorce and separation. Of course we love and care for someone. Were only human. Especially women. The only people who stick together are either unhappy and just deal with it, or are extremely content with monogamy... which is rare. People cheat because its in their nature to not want to just be with one person, or because theyre not getting what they want from that person... and I dont think anybody knows what they really want. So in the end, it rarely works out. This is my honest opinion. I say this out of experience.
