Love this thread. Was thinking of starting something similar myself. Please provide as many details as possible.
1) My IN-LAWS! I didn't know this until after H left. He doesn't remember it clearly, but his Mom reminded him that when he was young - maybe 6 or 8 - his Dad left. My H remembers it as only 6 months or so - I don't know how long it really was. Anyway, they actually got divorced. He then came back for good. They celebrated over 50 years together. She told me that her L asked her if she was sure when she was signing the D papers and her answer was that it didn't matter - if he loved her he'd be back and if he didn't, they would end up divorced anyway. I keep trying to hold onto that. It is the reality. Still it's hard.
2) Yes, ece711!! At perhaps my lowest point, just after I filed, I went to a college reunion and spoke to a friend. She and another guy in our dorm had dated through college and gotten married and had two kids, then things went downhill and she left. They got divorced. She said she had every intention in the world of just moving on. She dated other people and was actually living with someone else when a friend of hers made a comment one day about another couple, saying wouldn't it be nice to have someone that loved you that much and she realized she had that in her ex and that that was what she truly wanted, that she felt she and her ex were meant to be together. She went back and they remarried and had another kid and are happy now. It's only been a few years, but it seems solid. That story really helped me hang on.
3) I do have a third story of a guy at work whose wife left for about 3 years and then came back and they are together and seemingly doing well, very thankful that they were both still hanging on.
