You may struggle to grow as an independent person because you are too focused on someone else, and this can lead to a deep feeling of unhappiness. It can also stress your partner, creating unhappiness for them as well. Its effects can be even worse, damaging your emotional well-being, preventing you from forming healthy attachments to other people, and affecting your career. Long-term, your obsession could carry on to other relationships and cause you to repeat similar patterns.
