Im 35, she's 29. We are both professional people, earning good salaries, in jobs which require intelligence and common sense. I do know her, and myself well enough to know that we'd both make the right decision for both of us, especially now that things have calmed down and we can at least talk again. She has friends around her who will support her and make sure she's doing the right thing. I have no doubt that during the last week between me sending the letter, and her talking to me today, that she will have discussed what to do over and over again.
During a conversation I had recently I was told of somenes brother who had split with his wife, and she filed for divorce. the situation got messy, really messy. He was put on a restraining order, and not aloud to go near her.... 3 months later the restraining order was lifted, the divorce proceeding halted and they were back together and have been happy ever since. That was over 9 years ago.
I understand that you are making your judgements based on what I have told you, but I can assure you that there are other factors involved outside of whats happened over the last few months which would put the situation in a different light.
It will be ok.
