I don't even know:/ They both would break my heart</3

We all say "I hate you" from time to time. But I can't even imagine this one...

this must be so hard!! I mean, seeing someone you love just dating someone else hurts a lot...i cant imagine him saying I do to another girl!!

^This.

Having someone you love say they hate you would be horrible and very hard to deal with, but it could be fixed/dealt with a lot easier than watching that person marry someone else.

Well, I can't really relate, since I don't have a love of my life yet, which I'm quite thankful for, but still, saying "I hate you" is not nearly as bad. People say it a lot without meaning it. Saying "I do" to someone else is completely different, and to me, a hundred times more painful.

People do use the word hate a lot more than they should and a lot of the time they don't mean it. But if they were to go through a whole relationship, propose, go through the wedding and still say I do, you really start to think they don't love you anymore.

I can't see the love of my life (don't have one yet) say "I do" to someone else. No, I just can't.
Hearing the love of your life say "I hate you" to you is heartbreaking but I agree with Holly. It could be fixed/dealt .
