How many people actually talked to their ex's?

Hey I just want a few responses on who here actually talks to their Ex's. I just got me curious the other day. I don't and I feel kind of bad, but I don't think there's reason to talk. They do just ignore me a lot. The rare times I do have small convesations with them, I feel weird. So how many people talk to them? What do you talk about? Does it feel weird for you too? For those that don't, why don't you guys talk anymore? Thanks!!

ok heres my story:
1st boyfriend- went out with for 6 months when we were 15, he was a jerk, tried pressuring me to do things I wasnt ready for so he dumped me, he still calls about twice a year wanting to meet up to 'do things' I laugh everytime and say in your dreams and hang up, yet he still calls!

2nd boyfriend-was with for 2 years total computer nerd but I loved him, in the end he ended up telling me he thought he had feelings for someone else, I left him, we still talk now becos he wants to be with me still. unfortunetly I feel nothing towards him but friendship, but we say hi about once a week thru emails.

3rd boyfriend-was with for 3 years, topped the cake! was a cheater, abusive mentally and physically, suffered from depression and ocd, after years of dramas I left him just recently and have never been happier. I never want to speak to him again and will not be able to talk to him again if he trys to get into contact with me, its to painful.

I still talk to some of my ex-s....about 2 of them were my best friends when we started going out and we figured...just cause we don't like each other....doesn't me we have to hate each other...one of my ex-boyfriend's ________ we're so close he's like a brother to me...he moved out of state but we still talk about 3 or 4 times a week on the phone and a bit on the internet....so it all depends on who your comfortable around...just remember...just cause you don't like each other in that way...doesn't mean you have to hate each other or not talk to each other....hope I helped!
