Not everyone is emotionally mature enough to be in a relationship. Real, genuine, healthy relationships are built on mutual trust and respect, as well as the ability and desire to communicate about your issues — all things that an emotionally immature partner might struggle with. Of course, no one is perfect, but if you want your relationship to succeed, it's important that you're in touch with your emotions, and mature enough to acknowledge what you might need to improve on to become a better partner.
