Your definitely not alone....in fact I am in the same situation (minor differences aside)with having the unknown always telling me to try to reach out.....Honestly, listen to the DB' counselors, reread the book, get more information on as much as you can, and listen to those that are kind enough to share their experiences and advice here on these threads. It will take you a bit, but it will be well worth it! The number 1 thing you will find is that a better, more improve, educated, stronger you always looks better than what you (she) left behind. Plus the skill sets you are now discovering with help to circumvent future setbacks!
As for to the statistics....I agree, don't get too hung up on them, but the one thing I did find was that of those people that remarry, a second or third time, they stand a ball park 60-64% chance of failure with their 2nd, and 70-74% chance of failure with their 3rd marriages. But, of those couples who remarry an ex-spouse, and that population number is hard to find, but estimates have it around 10-15%, The success of that marriage to ex-spouses is in the 74% ranges, based primarily on all that was worked on and out by the individuals before they rejoin each other to reconcile.
Hang in there....stick to the process and allow it to work for you as you work on yourself. Relax, Breathe Deep...you have time on your side, use it to your advantage!
