I want to know how to forget about someone you loved but left you?

Sueann333,

Welcome to this wonderful site, first!

How can you be certain that he (or she?) loved you, when he (or she, whatever the case is) had left you. Ask him (or her) by phone, by person, by sms or by message. Is he (or she) in contact with you? What happened? What are the other options? Other points? Just relax, and time is a great healer, remember. Still, I want more info to give advice.

Give brief detail.
Welcome.
Good Luck!

You accept they have left because they don't love you like you love them, mourn your loss, heal, and rebuild a life that you enjoy, and move beyond this chapter of your life.

Getting dumped and rejected sucks, and hurts like hell for a while but in time, we get through it. Just give yourself the time to adjust.
