Sometimes its not just love issue. In christianity (evil eye), hinduism (nazar), pagans (jinx). I know some couple literally living happy life for years and some people jinxed by daily sending issues on their life. This is one of the reason I heard many grandma's or pa's tell their grand kids never to tell other people that everything is good with your life, always something I have car but its so slow, I have husband but he drinks or snores and is argumentative type. love often is not reason to prosper forever sometimes many elements attack psychological, spiritual, social.
