I have broke up with my gf 2 months ago and she has got a new bf now. But still we talk with each other regularly as a frnd. Even after knowing and getting enough proof that she has a bew bf, whenever I talk with her, I get attracted to her. My mind knows all the truths of her current relationship but still I my heart is attracted and attached with her. My friends make me understand that I will get better girls than her but my hearts don't bother that, still my heart wants to have her although she is telling that she won't be mine anymore, forever.I'm thinking about her all the day which is hampering my concentration on job, career etc. What can I do to avoid these heartily stupidity?
