God blessed you so that you can become a blessing to others. That may be true in some instances, but in others it doesn't hold water. When God brought King David back into his kingdom, Absalom, his son, who tried to kill him and take his father's kingdom, that same Absalom was deservedly killed by Joab, because David loved Absalom and didn't have the heart to kill him. Consequently, he asked that Absalom's life be spared. But Joab, not blinded by a stupid love, saw the wisdom in swift justice for the usurper and carried out the task against the king's wishes.
Sometimes we love the very people who are trying to destroy and/or to literally kill us, but that is no reason to allow them to abuse that love. Leech-like mentalities often come wearing the faces of those the closest to us. There is nothing that you can do about that, but refer to the word.
"Think not that I am come to send peace on earth: I came not to send peace, but a sword. For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter in law against her mother in law. And a man's foes shall be they of his own household. He that loveth father or mother more than me is not worthy of me: and he that loveth son or daughter more than me is not worthy of me. And he that taketh not his cross, and followeth after me, is not worthy of me" (Matthew 10:34-38).
Your cross is to do the will of God, and in the process you will suffer loss. That loss will invariably be relationships, that if you hold on to them, will destroy you, because Satan will use your love against you, making you vulnerable to those near you who he will use to destroy you.
If Joab had not killed Absalom there is no telling what additional havoc he would have caused King David. Satan turned against God and did the exact same thing. He tried to usurp God's kingdom and God cast him out of heaven to face an eternal hell; a world where the damned dwell. So be careful who you invite into the inner circle of your life, because the eternally damned have nothing to lose. It is their chief joy to destroy silly souls.
It doesn't matter how close the relationship, as a matter of fact, the closer the relationship, the more alert you should be. If you keep experiencing pain from a relationship, it's time to let it go. This is not the Old Testament times where we can just kill our enemies, we are not literally kings or queens with that kind of power, but we can separate ourselves from our enemies quite adroitly.
Yes, I know we are suppose to love our enemies. This is true, but there are some enemies that you love from afar off. You hope and pray that they repent and allow God to change their lives. But there are some enemies that God himself has cut off from any possibility of eternal life, those are the very dangerous ones to steer clear of, and please, please don't pray for who God has determined for destruction. God might answer your prayer and you will be stuck with a life-long enemy whose only purpose is to destroy you because you did not accept God's judgment, that God knew what he was doing when he cut the evil one off from eternal life in his holy presence.
Consequently, you will live with a foolish prayer trying to save someone's soul who had already demonstrated to God that he/she was unworthy of salvation. Never try, because of the tenderness of your heart, to undo the judgment of God when it comes. Let it be, or you will pay a dire price. I cannot stress this enough! Trust God that he knows all the facts, every detail about the person he has judged, whereas you may know very little, and are operating without full knowledge.
Whatever you lose God blesses you with more and better. So don't fret if you have to cut a long time friend loose or keep some relatives at a distance. Those critical choices could save you a whole world full of suffering.
What stage are you in, vindication, judgment or recompense? If you are not in either, just wait for the cycle to turn in your favor. Go through the storm and get to the other side where your blessings are waiting for you to arrive.
