#6 Distance yourself from memories of her. Yes, that means if you met her at your favorite place to get drinks, you should avoid it for a while. Just try to stay away from anything that reminds you of her.
The fewer reminders you have, the less you’ll think about her. And eventually, you won’t think about her at all anymore. She’ll just be a distant memory that only pops up once in a while.
#7 Remember why you can’t have her. It’s not enough just to acknowledge that she’s taken. You have to remember that she’s happy with that person. Even if you can’t stop thinking about her, she’s still enjoying life with someone else.
And you’d be an awful person for trying to ruin that for her. This should help you accept that you can’t have her so you can work on moving on.
