I go along with second chances.

Not always but, sometimes, giving another chance it's okey at all. I mean that if you're in love it's not easy taking a decision like this. You really must value all the things you're going to lose without giving that chance and all you can win instead. Unless you were totally sure, try giving the chance... Maybe it will worth it. And if not... If it doesn't work again don't panic and stop regreting because it won't solve anything. Always try to take the decision you think will make you as happy as possible. Life is short, spend it on making happy yourself and also on making happy the people who are important for you. Through it all, sometimes life will reward you. Don't forget.
