Have faith God has plans for you to prosper and not to harm you (Jer.29:11)
You may never know or understand why the break-up happened; however, God may be protecting you from this person, He may want you all to himself at this time or he may have someone better suited for you. Whatever the reason, God knows our beginning, the middle and the end and truly wants the best for us, as our Father. Have the faith to recognize it, believe it and live it.
Place your hope in God and his Spirit, not in someone else (Rom. 5:5)It may be difficult to do at times, but placing your hope in a perfect God is a better decision than giving your life to a fallible human. God continually shows this to be true in ways we can’t even fathom and hope placed in him does not disappoint. I’m not sure we can say the same about others, or ourselves.
Show love for everyone (including your “ex”) (Matt. 5:43).
Love in today’s society seems to be so fleeting and have no basis at times. The love God teaches us is neither selfish nor affected by emotions or situation, but rather loves through all things, including trials, faults and disappointments.
The most difficult part, as you have mentioned, is to see your former interest around work or at church, especially if he or she is with someone else. However, when you reach that point in your healing and forgiveness process when you will want the other person to be happy even if it doesn’t include you, you will find a peace that really does transcend all (human) understanding.
This isn’t an easy process, it will take time and there is no perfect “formula,” but it all begins with releasing any negative feelings you have toward your former partner, forgiving them for whatever wrong they may have done, asking the Lord to heal you of your hurt and pain and holding onto hope, faith and love.
When the next opportunity comes around, and there will be more, you will be better equipped to handle whatever that situation holds.
The LORD is close to the brokenhearted and saves those who are crushed in spirit
