In the rut..

I know this guy for a decade, and I think I am too obsessed with him. We lived together for two years, and 2 years back he kicked me and my child out of his place. But I still could not get over him. We live in the same neighborhood, as my child goes to school there and I have not seen him physically for 8 months. But we are still connected with him through email and texts. I cannot imagine my life without him. I am starting a no contact period which should last for ever ( I sincerely hope).
