I’ve become extremely obsessed with a man who hardly even knew me, how do I stop this?

I have a really strange relationship with men outside of my family. I either don’t want anything to do with them or I secretly become obsessed with them, idolize them and romanticize every single thing about them when they hardly even know of my existence. 

This happened to me recently with a Russian painter who came to paint my family’s house. He stayed for 2 weeks and was at my house everyday from 9 am to 9 pm. I fell so deeply in love with him in those 2 weeks. His quick temper, his passion for painting, all the hard work he put in to attain perfection and his struggle to manage his team of workers just made me his obsessive lover. He had a lot of conflicts with my parents who were extremely demanding during the whole process. He did not meet his deadline and my parents were pissed but he was resilient throughout. He had a meltdown on the 5th day and swore he’d never comeback but he did.

It’s been 2 weeks since he left the house and I’m still obsessively thinking about him. How do I stop? I think I have serious issues. I became way too emotionally attached to him.
