I my sound to be questioning my question, but feelings and love can’t fade away. They might be hidden somewhere or clouded by some other emotion, they cannot go away. Try to find it. If you think your partner is acting different or indifferent, try to love her more, trust her more and everything will be normal. Feelings can never change, it’s time i.e. changing and with time that passion and that romance can all become a little less. Love is not changing, the manner of expressing it could be changing.
