I broke up with my ex 6 weeks ago and after a couple of weeks I started to feel less like my world had ended... then he got back in touch. He begged and pleaded with me to meet him and like an idiot I went and we slept together. He messed around with my head for a few weeks and now I’ve cut all contact with him but I feel miserable! I know he will find a way to get in contact with me again, how do I stop myself from going back? It’s like a drug addiction! I know he’s awful to me but still fun as soon as he gets in touch. It’s been 3 years of turmoil... how do I break free?
