Endings are never a good thing but the old cliche is true... Time heals all wounds. I've been separated 3 years now and even though the decision to leave was mine it is wasnt easy. Some people like to surround themselves with family and friends others like to go it alone and take that time to heal themselves.... The choice is yours. Just don't dwell on the negative aspects of divorce everything happens for a reason and when one path ends another one begins.
Look, all these answers are nothing more than OPINIONS! There is no fool-proof way to deal with divorce. As hard and unfortunate as it is, divorce happens to many many kids just like you all the time. My best advice is to talk with both parents, at the same time if possible...that would be even better, and express and I mean really express what their splitting up is doing to you both emotionally, mentally and physically. Don't worry about hurting anybody's feelings. You're a kid and the LAST thing on your mind should be the turmoils of your parents' marriage. Most importantly, make sure each parent REALLY hear you...from where it really matters...your heart! You be strong, concentrate on school so that you can get a good education and no matter what, STILL love each parent just the same. Don't think for the slightest second that you did something to break them up because you did not! I dont know you, but I love you, little brother/sister. Really hope things work out!
