When i do speak to him i start missing and thinking about him which i don't want to do hes my EX. But anyway ive asked him twice not to call me anymore , So what he does is wait 2 weeks and same thing i get a call from him Sat night same time. He called Sat but my phone was off all day so he left a voice mail telling me that he loves me and misses me to call him back. I honestly think that when he does call he has been drinking, But i dont know what to think of the whole thing? Should i call him back? Im thinking about changing my number should I? Or what does he expect to acomplish with our converstaions? i would really like to hear someones opinion thnks.....
