moving on help: How long should it take to get over someone? - Help.com

Well, depending on if he enjoys your company, it ain’t a problem. If he’s irrated by it, then yeah, you are buggin him a little too much.

the amount of time depends on your personal strength. obviously you’ll never get over at him if you purposely run into him at every given situation. if you really want to get over him, you will avoid him at all costs. you will tell your friends not to speak of him, you will stop speaking to people you only talk to/see because of him. you will get rid of every significant memory you have of him. you will refrain from calling, emailing, texting.
if you want to get over him, do it! if not, stop complaining and ask for him back, if he’ll have you.

The best way to get over somebody is to get under someone else as soon as possible. Try to express more love for yourself, after all you can only give away what you have for yourself. Continue to see your boyfriend, be sure to extend your love and kindness to him. Step back from “what’s in it for me?” and detach yourself from expectation. Be thankful and fully present in the moment when you are with him. Keep your wits about you, as there may be a brand new opportunity for romance around the corner…

someone told me once, that for however long you went out with the person for, it generally takes about half that time to “get over them”, and then you add some more time on for if they cheated, if you were engaged etc.
so theres a general guide, ive found it to be pretty true too.
