Not sure if it's my place to comment, but this and your last article seem to indicate it might be a bit of a rocky patch for you in terms of love.
I just wanted to reach out and say that it's okay if love fades, and I don't think there is a pressure to love someone unconditionally. Someone you love has done a lot to earn it, and it should never be brushed away that there are reasons why you love them, and that it is okay if your reasons for loving change, or no longer fit, or anything.
More importantly though is the dialogue between you and your partner, to see what everyone needs from the relationship, and when that is being delivered. When are your fears rational vs irrational, and what inspires them, and does this mean they should try harder to alleviate concerns.
I admire your faith, but hope that there is also great communication and understanding that underpins your trust. It's less romantic, but more solid.
