X-gf/bf who keeps on communicating though he/she has a gf/bf already..

it depends, maybe he just want the both of you be friends. u can feel it whats his real intention! If i were in that situation, I'll stop communicating with him even he just wants me as a friend.. I wont even trust someone like him eben just a friend.

fool me once, shame on you...fool me twice, shame on me...that would be a big no no for me! cheat on me once, we can still work it out...cheat on me twice, you think iam a fool!?...get lost man! i would say...he/she is a player so don't get played by them. ..you had enough so don't ask for more.

even if they wanted to be just friends i would still tell him/her to go f*ck themselves. after cheating on you multiple times??!! that person has some gall to continue trying to communicate with you. dont waste your time or breath for more than to tell him/her that you never want to hear his/her voice again.

Here is a solutin that i can probably provide to u. Well i thing a person would fall in love only when there is a emotional attachment, a fulfillment of criterias and desires. However for certain mismatch if the relation has broken and u have accepted back the person,i would say u r a true lover with a big heart. However since the person has neither faith on you nor the new love of his/her. So even if the person has realised his/her mistake and wants to get back to u. I feel that person is not even worth being entertained. If u accept the person then also be prepared for another heartbreak. Now its all upto u.
