How long does it take to move on?

Ik it’s a dumb question but oh well. I was in a relationship for about a year and for most of it we had an amazing connection and were so close. I have no one now that he’s gone. It’s been a while and I still feel like it was yesterday and I just don’t understand. How long does it take, ppl are really confused when they find out I’m still mourning over him and I just feel so weak and pathetic, I would move on if I could. I’ve tried but I just, can’t. I still love him, and hurt to see him move on, being without him and just knowing he’s entertaining someone else drains me physically and emotionally. I’ve tried hobbies, checking out other guys but I have no attraction to them at all, I feel disgusted at the thought of being w anyone other that him. I need help, all I see is “all I need is time, or time will heal a broken heart”. How much time UGHJJDKEDLLF
