There's no set time period for moving on from unrequited love. Everyone goes at a different pace. However, there are some signs that you're ready to move on from the person who wasn't interested in loving you.  You start noticing what is going on with other people. A lot of times when you're in the grieving stage you tend to get a little self-absorbed. When you start taking an interest in what everyone else has been doing you'll find that you're well on your way into the healing process. You've stopped wondering if it's the other person every time you get a call (especially if it's from a number you don't recognize). You've stopped seeing your own story in songs and movies about unrequited love. In fact, you've started expanding your repertoire to include things that aren't about love, or the pain of love. You've stopped fantasizing about your unrequited love suddenly coming to the realization that s/he does, in fact, love you and always has. Even when you're ready to move on, you can sometimes hit a relapse if you're not careful. It's like taking the stitches out of a wound too early. It's healing up nicely, but it's not ready for strenuous exercise quite yet.  Avoid doing things with the other person or letting him/her back into your life until you're sure that this won't cause you to get back on the swoon-train. If you do find yourself relapsing, don't sweat it too much! You've already put in a lot of work to get over them and that work will pay off. Setbacks happen and if you give up right away, it will be harder in the long run. Put yourself out there, meet new people, flirt, and remind yourself how great it feels to be a catch. Your confidence surely needs the boost – and in the meantime, you’ll meet interesting new people. In fact, every time someone is better in some way than the person you’ve been chasing – better looking, funnier, smarter, more down to earth – make note of it. It’ll put things into perspective.  You don't necessarily have to be on the look-out for a new relationship. Just enjoying the presence of new people can be a big pick-me-up. Be very careful with rebounding. While sometimes a rebound is just what the doctor ordered, it only works when you’re emotionally ready for it, you’re honest with yourself about the fact that it’s a rebound, and you’re honest with the other person about the fact that it’s a rebound. Don’t make this new person feel as miserably in love with you as you are with the person you’re trying to get over. Getting over someone you're in love with isn't easy! Any steps you make towards getting over the other person should be celebrated. You should also remember that just because this person didn't return your love doesn't mean that no one will.

Summary:
Know when you're ready to move on. Avoid relapse. Get back in the game. Stay encouraged.
