Lol That first ones a doozy, ain't it!?
I remember being in middle school, my first year, broke up with a girl...whatever that meant at that age, and I was crushedddd. For like a week. After that it becomes a game of "liking girls......but not too much, cause' no ones gonna' make me feel that way again!" Ahhhh those adolescent years lol.
As for who moves on faster? I think that would be based on the individual. If one is ready to move on and the other isn't, guess who's going to be in a situation?
-Off topic, kinda:
All in all though, I wouldn't suggest getting involved with anyone unless they Love Christ more than they love themselves and you. That kind of selflessness, I believe would let you have a long lasting, meaningful relationship. I mean in troubling times, you would have 2 heads instead of one seeking wisdom and support from the most high. Now I may be naive in this regard, but someone who loves Christ more than they love themselves, more than they love their partner....I don't see how that person would ever seek another partner to begin with. But then again, we're all human at the end of the day...who knows if today is that day where John or Jane Doe choose themselves over God and their partner at that moment, and sever that relationship. So, even if you are the victim, you'll always have Jesus to look to. But knowing what I know about heartbreak, will that help? Not at first, but I think the True Faith would help you move on. No matter what though, you'll never know unless you take the chance. Just be wise about it.
