Cara -I am so so sorry about your father and am crying reading your post. I am sure he is in a better place now and will always be with you. You sound very strong and I am sure he would be proud of you for continuing on wtih your wedding. He will be there in spirit.
And Christina- also crying b/c of your post. Im so sorry about being blindsided by your ex-FI. They say everything happens for a reason, even if we cant see it right away. The only thing I have ever been able to tell myself when I have went through break ups is that I deserved to be with someone who 100% wanted to be with me, and if htey didnt then they didnt deserve me. And obviously your ex was not the one for you. And if anything, at least it happened now before you made this marriage committment. *Hugs*
