Wow, I hadn't given it thought like that. I'll be sure to be cautious next time. This really helps me feel a lot better about the situation and myself. You're right, this is a powerful lesson I will keep with me for my future endeavors. I'll be sure to develop myself more as a person as well, as you've said, Open Eyes, and really get to know the next one as friends. You were right, I was eager to give away my heart, I thought in a way this was the end of the road for me, because, in my mind, she was the one, and there would be no one better. I really began thinking about our future already and was ready to change my life accordingly. Now that I read that to myself, it sounds very irrational and irresponsible of me to do that to myself, and the other person, especially if they aren't ready to commit on that level yet, and/or we haven't been together long enough. Given the circumstances, heh...
You guys have made things more clear for me, and I respect and take in every opinion.

To conclude. I will be more careful next time. Take time instead of jumping into things. I will be more respectful, clear and considerate. Thank you, everyone. I'll just need to take time to let these emotions flow through at this point.
