What about you? Ever thought about getting married some day?
I don't really have strong feelings about it one way or another.
Besides, a lot of the people I date tend to be married already.
Huh. Don't you ever worry that that turns you into some kind of... I don't know...homewrecker?
Aha, you've found me out! Behold, my iron-clad marriage-destroying plan:
First I make sure to meet the spouse and check in that everything is ok and above water.
Then I form a close and supportive friendship with them.
Then I try to help out around the house to show respect and care for the home they're invited me to share with them.
Finally, I try to show through actions and words:
Hey! I want you to know that I honour and care for you as a couple and I am happy to be in your lives! I consider the health of your relationship to be a key contributor to the health of my relationship!
