Attracting my ex colleague

I worked with this guy and we both were pretty much into eachother. Smiles and chit chat here and there. But then suddenly he changed. He stopped paying attention to me. And then i quit my job. Now I CAN'T STOP THINKING ABOUT HIM. IT'S LIKE I NEED HIM. I WANT HIM. We are completely out of touch

I took initiatives sent him a friend request which he accepted a week later. Now it's obvious he doesnt even care about me. But i want him to feel me calling out for him. I'm trying telepathy. Law of attraction. Nothing is working.

And btw I'm married. And i just wanna be friend's with him.
