Of course, it is not easy to leave a loved one; always difficult and takes a fair amount of time. However, if it is necessary, due to a very reasonable, and an important cause, then leaving a loved one must be attempted. So, while it still takes time (everyone is different) to cool off, leaving someone you love can be done by finding someone new (thankfully getting a better one). Then, learn to love this new person. Remember, love can grow alone or with a learning/effort process. Remember, love is everyone's need (we can love and beloved by anyone in this life), while he/she may have his/her own destiny (not us). If this succeeds, then you have been freed from a great danger; our dependence on (his/her) love which is not always good (it depends on the case). Remember, one day, we will leave him/her, or he/she will leave us; one of the reasons is death.
