Once you genuinely love someone, that love doesn't leave, because they left. Your love for them, however, will have to manifest itself differently. You're going to have to accept loving them from a distance. No contact or communication. Say your prayers and wish them well. Having love for them doesn't necessarily mean that you have to pursue them. Loving them from afar may be the best solution for you.
Theme for life. I have spent a lot of time kicking myself for hurt I caused but at some point letting go is all the power we have so I let go of those who said they love no matter what, they don't and I can't own that so this Monday I say good-bye! I will love forever from a distance.
