For me the only acceptable third party in any relationship is ''GOD''... for my self,, i always put god in everything i do.. He is so great! He gave this special and wonderful life to me and im very thankful for that, and even in my church i saw a lot of lovers and couples who live their lifes very happy to their loved ones kada sharing magpasalamat jud na sila sa ginoo kay bisan kuno naay mga trials na muabot sa ilang relation maka survive gehapon sila..mutuo ba mo na mao cguro di magdugay ang relation sa uban labi na sa mga mag uyab kay tungod god is not the center of their relationship? do you accept him as a third party in your relation?
