If you’ve had a breakup, you’re probably either trying to figure out how to get over the person, or how to return lost love. Neither is very easy, but most people fall to one or the other, with only very few able to move on quickly without pining or wishing things could be different. You should really think hard about the relationship and your ex before you do anything. Think about how things were and how they will be now. Try to be as unbiased as you can. You might decide that the breakup really isn’t a bad idea.
If you decide to try to return lost love, the first step is to apologize. You might think you’ve done this. You might have said you were sorry several times. But if your ex thought you were apologizing just to stop a breakup, he or she might not think the apology was sincere.
If you were the one who did something that you need to apologize for, apologize again. Now they might think the apology is sincere, because nothing hinges on it. If the relationship has ended, you won’t be saying it only to save it but they will believe that you really mean it. (And hopefully, you do.)
When your ex was the one who did something worth apologizing for, then rather than try to get a sincere apology from them, forgive them. You may never forget, especially if your breakup was because of cheating, but you must learn to forgive. Forgiving is much harder for some of us than merely saying, “I forgive you,” though, so you might want to read a book or two on forgiveness and how to really mean it. If you want to return lost love, this step will help you do it. And it can help prevent problems in the future, too.
If you do succeed and you return lost love, 3 or 6 or 9 months into the newly patched relationship, old issues might come up. If you haven’t forgiven the person for whatever was done to break up the relationship, then you might have a hard time getting past everything. Old wounds would be reopened and it’s likely that hurtful things would be said.
But if you can truly forgive the person, then there won’t be any need to rehash the past. While you’re working on forgiving him or her for whatever happened to cause the breakup, forgive them for the breakup itself and you’ll save yourself lots of grief down the road.
Also, to return lost love, show the person the "you" they fell in love with, not the “you” that has been dumped. They were with you because you have certain qualities—kindness, thoughtfulness—not because you’re angry, jealous or hurt. While you might not be able to hide the hurt, concentrate on being the best "you" you can possibly be and you may return lost love by reminding them why they loved you in the first place.
