Both partners willing to commit time to it. Caring and compassion, understanding, past drama that both partners will bring into the relationship. Your readiness for the relationship, and if you are seeing others or even interested in others. Family and social ties. Timing and luck. Money has nothing to do with it, whether they both want kids etc.List could go on and on, I'm thinking lotto might be easier.
Lot of Miley Cyrus and Ariana Grande. Also Taylor Swift and Justin Timberlake. Throw in some Prince and Queen. Bit of a mixture. I don't mind Tones and I either.
