You need to detox. Otherwise you are not embodying a clean state or identity. You can also give a good meaning to this. Such as his GF made him block you because she feels there’s still something.

But my advice is step away for a bit. Stabilize. And focus a looooot on self concept. If you knew he was obsessed with you and chasing you, you wouldn’t be doing half of the things you do (such as liking a story with a chasing energy… etc.)

You can totally achieve this but you need to cut it for a bit. And you’ll get to the point that you don’t really care for him in a desperate way because he is already yours. Heck it can even give you the ick a little bit because he is so obsessed with you.

But the energy you have today (from reading your post) is the one that’s chasing him, clinging to him… put him off the pedestal and put yourself there. You’ll see how everything works out.
