Relationships are built on interest, connection, and general likability.
This applies to all levels, be it romantic, friendly, or even just "acquaintance".
God doesn't come into the equation. Hate to break it to you, but you aren't a special snowflake. God doesn't "match people together" on any scale, in any religion.
People might want to interpret the text as "god cares about me and does everything for me" but he doesn't, nor should there be a higher priority on short romances versus real problems with the world.(hey, god will get around to war, famine, slavery, and all that jazz eventually.....right?).
But yeah, religion is pretty much as relevant as movie taste or general dislikes. If your an ass about it(either way) then it's going to conflict with the relationship.
