Well, there's not much I can really say about this week-long "relationship". I wouldn't call it a waste of my time, because like all relationships and events do, this small relationship taught me several things.
It taught me to not let my guard down so soon, that even if someone says one thing, they might really mean the total opposite. It taught me that trust is a hard thing to earn, and once you lose my trust, you will never get it back. You said all of the right things, so much so that I made sure to ask you if you were just telling me what every girl wants to hear, and that you were too good to be true. You said no, but I'm glad that I know the truth.
I also learned that there should be no double-standards, especially not in a relationship. You got mad because of my guy friends, but it was cool if you texted other girls because they were "your friends". However, this was not cool.
This week-long relationship also helped me to expand on the qualities I would want my future husband to have. The problem we had was a difference in religion. To me, my faith is an extremely huge part of my life, and I want to make sure that I have that in common with the next person I have a relationship with.
I learned that people who move on too fast from their last relationship don't think about other's feelings, and will jump into another relationship. You definitely did this, and ending up hurting not one, but two people in the process. I honestly felt sorry for you because of the way your ex was talking to you, but now I can't say that I blame her at all.
Ultimately, I learned that you can never be friends with an ex, no matter how brief the relationship was. After we broke up, you basically begged me to still be friends with you, to which I agreed. I saw you as a caring person, and I respected you for who you were. We talked everyday, and acted like nothing had happened. Soon though, you became distant and stopped talking to me. Not to my surprise though, you said you had met someone. I didn't understand why this would matter seeing that we were just friends. Now, however, I'm thankful that everything happened the way that it did. It taught me lessons that will prepare me for the guy that will actually be worth my time.
