No contact is the only way to go and it is painful but you will heal quicker. Staying friends and talking, being in his life prolongs your heart from letting go and you’ll stay on that awful ride of the emotional roller coaster. I just posted something similar to your thread here actually. Hope it can help you as well…

I say, let the anger out, write down what you feel and why. It’ll help give yourself closure and also let you grieve the loss, let go of hope and make you see that he isn’t worth fighting for. His loss, though I’m sure it doesn’t feel that way right now.

I am grieving too, still and it’s going to take a while to heal. Just be good to yourself, most of all. No point of regret and beating up on yourself with the ‘I should have done this or that’ thoughts…All that does is make you feel worse and sad.

Stay strong and vent it out as much as you can. Most of all? Keep your humour going and make sure to really laugh and have fun with your friends, it lifts your spirits up and is so helpful.

Take care.
