If you love him and you stay friends with him, I honestly think you are likely setting yourself up for heartbreak. It’s ultimately your decision and sure it could work out, but I’m most cases that I know of it makes it a lot harder to get over them emotionally and if they don’t want to date you and you stay friends with them, the day may come when they begin dating someone else.
So yeah, it’s not something I recommend when one person want more than the other one. If your already hooked on them, you’ll stay hooked on them because they are still vividly in your life.
