do you think a girl and a guy can really become close after they become lovers?

there's nothing wrong with it.. as long as you respect each other, and always keep your secrets you can always be in good friends.

actually it depends on the foundation that couples have established before they decided to become lovers. i think there's a bigger chance of becoming very much close friends of your ex if it happens that he/she is your long time friend right before you became lovers. :)

it is possible because it happened to me. my ex girlfriend is my close friend now. we help in each other's work. she asks for my assistance and sometimes i also seek her help in my work. but i heard stories that for some people, this is difficult. the breakup seemed to be hard to accept and the familiarity of each other keeps a distance to each other. in my case, i like my situation now.

why not jen??? I am that way with all my Exes and we share a very nice friendship after break-up...

nope. of course not. when u really love someone, there is no way u can tolerate to see him/her with someone else and doin some stuff u know... it makes me sick, i experienced before and its like hell. at least for me.
