Call from the ex

so last night I was feeling pretty sad anyways, things haven't been going too great lately. then out of the blue my ex girlfriend called me up who I haven't spoken to for a good five months now over the phone. we were trying to be friends by texting each other but it's been hard because her new beau (who was her first ex too) doesn't like me very much and won't let her talk to me. I told her it would be better if I wasn't in her life anymore and she said she wanted to hear my voice one last time before we said goodbye for good. I was dominant I didn't wanna do this, I was already crying but I did the decent thing and let her call me. what followed was horrible. it was an hour of me and her crying to each other over the phone. I've never heard her cry before and it broke my heart!! I couldn't say anything to her because I know I hurt her just like she did to me last year. there's always part of me which will always love her, she was my first proper relationship. she'll meet forgive me for doing this anyway. I learnt a lot last night. I learnt I'm a lot stronger than I used to be and dealing with that has made me realise that I can do it but it also hurts me when I do. I've finally learnt to let go.
