I think the only time this can genuinely happen is if the break-up was rather mutual, or mostly mutual, like if the couple started drifting apart.
I've seen people become good friends with their ex in these scenarios, but not in those devastating heartbreak scenarios where one person was not at all ready to break up.
I put "no" because in those cases, it doesn't mean the couple never loved each other at all. There's no guarantee that who you fall in love with will be your love for the rest of your life. People change, get older, mature, change character, sometimes even change interests.
I tried to stay friends with my ex boyfriend and that did not go well because we both realized that we loved each other too much to see one another with someone else or we couldn't stand being "just friendly" with one another. I was willing to do anything to make it work out for the both of us; i really wanted to be friends because it meant that he would stay by my side for at least longer than he should... It ended up being an disaster because we just realized how much we wanted to get back together but we can't. So based on my experiences, I'll say yes. You can only be friends with your ex because you still love them or you never loved them in the first place...
uh... sorry but isn't that everyone not just ex's? And usually one person is in love with the other. I don't know why girls think its great being friends with their ex's... oh... it causes drama... forgot that drama is important to women.
My ex husband of 15 years and I are friends. We're actually better now that we're divorced than when we were together, in terms of getting along and being on the same wavelength regarding our son. I know if I really needed anything he would help me and vice versa. I did truly love him back in the day, but our relationship just didn't work out. The all-or-nothing mentality is kind of immature.
