It should be more like:
"I'm taking a leap of faith with this person I'm deeply in love with. I know, there are no guarantees in life. If things don't work out, I want to be fair and maintain a good standad of living for myself and our kids (if any). If this relationship ends, I don't want to be blind sided or be in a situation where I'll HATE this person I'm currently in love with. I want to put all my cards on the table right now and discuss directions we should take and reach a mutual agreement now in the even that things don't work out in the future."
