You can do it. It's just extremely difficult, unfair, and traumatizing. The pain is worse than anyone can realize. It's exceptionally hard even when time has passed and you've made so much progress moving on but the divorce papers force you to go through another round of grief when you're already tired from all this. Just like you I know that if / when I receive divorce papers I'll feel the same, like I just can't do it. Why don't you write everything that's going through your mind here and we can listen and respond?
Manta and Destroyd, when I joined first joined this forum many members were writing about how they know each other in real life. I asked how they met and it was through facebook. More recently one member (and I think I realize now who he is!) created a secret facebook group called "The DB Society." If you want to join he may accept you! I had a few good conversations with members there. If you do join, you'll probably be able to figure out who I am so please say hi! :-)
Side note - to the member who created the DB Society group, if you read this, I just checked the group and your profile and wow, your girlfriend / significant other is gorgeous!!! You two look great together! That gives me hope that maybe I'll find someone someday.
