This is awful. I never expected my love to cheat. I never expected to lose the mother of my child.

This sounds raw for you so I assume this happened recently.

What worked for me was writing down about how I was feeling each day. I drafted many letters about my anger but didn't intend to post them but getting my feelings out on to paper/computer helped me a lot.

Focus now on yourself and be kind to yourself too. You'll go through all the different stages; grief, anger, bewilderment, the whole shebang. Your world has changed. It's all part of the process of healing oneself. Just know that there will be light at the end of the tunnel and it WILL get better although you think it won't.

Time is a healer.

Most of us have passed that way at least once m8. I recon you've been through worse. I know I have.
Listen to Delightfull. Good advice. better than thinking the same jumbled thoughts over and over. take care of yourself.

Met my ex wife recently, I really couldn't understand why I made such a fuss, I really couldn't. Flipping woman.
