How do i get an ex to stop ';checking to see how i'm doing'; after a painful breakup?

i went through a pretty painful breakup with someone - its been about 6 months and i've started dating someone i really care about.


the guy i was with still feels the need to text or email every so often to ';check on me'; or to ';see how i'm doing'; i know his intentions are good..but i feel the heartbreak all over again every time i hear from him.





i've asked him to stop politely and he will for a month or so, but i always end up hearing from him.


he claims to want to stay in touch and be friends - but i feel like i'm going to vomit every time i hear from him.





what should i do?How do i get an ex to stop ';checking to see how i'm doing'; after a painful breakup?
be honest, ';look, i honestly just do not feel comfortable being friends with you, i just dont want to stay in touch.i wish you the best of luck with everything.';
