After waiting like all my life, why do i want another guy?

The grass is not always greener on the other side. Watch yourself here because you may hurt a very nice guy, and someone who you have known for a very long time. It sounds like a sweet relationship you have with Sam, do you really want to go with a guy who is practically a stranger. I'm sure a lot of people are going to tell you to dump Sam and date Adam, but you would be making a huge mistake. Someone once told me that the heart wants what the heart wants, that same person cheated on his awesome wife, and deeply regretted it.
