Intelligent Design Theorist: Our relationship bears the marks of irreducible complexity making it too difficult to explain by way of natural causes. Therefore, there the most reasonable conclusion is that we were designed to break up since things have gotten so complicated.
Calvinist: We were predestined before the creation of the world to break up according to God's good pleasure. I am, on my own power, unable to break up with you apart from the irresistible draw of God's sovereign grace which leads me to end this relationship. Those that truly break up will not get back together in the end.
Arminian: While you love me and have a wonderful plan for my life, I have the power to resist your will. If I did not, love would not be possible. For our relationship to be loving it needs to include the possibility of breaking up--something I am doing right now.
New Perspective on Paul Scholar: Rather than earning God's blessing, it is established on the basis of our covenant courtship (I asked your dad to date you didn't I?) which requires the proper response of an intentional and deliberate pursuit of marriage. Yet there is no such pursuit, therefore God's blessing on or relationship is no longer maintained.
Open Theist: I am not really sure if we are supposed to be together, because neither is God.
And the very best one for last:
Episcopalian: Ummm... I'm gay.
