Human beings learn more through experience than through any other means. Therefore, you may evolve to find something good related to every relationship you have ever had.
You may not realize that your higher self is involved in helping you create each of your relationships. That is, part of you has motives and intentions that your conscious mind only realizes at the right time. Consider 5 ways to reframe broken or past relationships;
1) What if you created a relationship which would teach you the value of your self-worth? Allowing yourself to be mistreated or exploited is a lesson in defining boundaries. Only you ever determine your own self-worth. No one ever intimidates you without your consent.
2) What if you attacted a relationship based on your lingering broken heart? If you attract a person who acts such that painful history repeats itself, then that person bears some responsibility. Yet, that person would also be encouraging you to grow.
3) What if you enter into a relationship that does not work out due to your naivete or inexperience? This may draw your attention to how not to perceive yourself as a victim.
4) What if you have faith that your partner will change to suit you and this does not happen? This reminds you that you are only ever able or meant to change yourself.
5) What if you evolve away from or outgrow your relationship? People grow in different directions. People who choose to grow together tend to stay together. People who do not choose to understand or support another are choosing to stay where they are.
