Crazy people

It's kinda crazy how much of a difference a few days can make. A few days ago I wrote that I wasn't in the market for anything serious. Gus commented on my post and asked if I wasn't interested in anything else why was I spending so much time with Marcy. That really got me thinking, why do I do stuff with her so much? This is what I came up with.
I really do like Marcy. At first things were rough with her. They were awkward and confusing. But as time has gone on they get easier and easier. I have so much fun with her now. So to answer the question from Gus, I'm spending so much time with her because I like her. I actually like her a lot. Yesterday Marcy headed down to Utah to spend a few days at her sister's house before she flies home for the break. I spent the day snowboarding but I went over to see her before I headed up to the hill. As I was leaving I gave her a hug. One of the good ones where you never want to let go. And she looked up at me and I couldn't help it. I kissed her. It was great. Was right up until the time when I had to leave.
On the way home from boarding I was texting her and she asked if we were dating. I asked her if she thought we were and she said yes. She asked if I wanted to be dating. So I thought about it and realized that I really do want to date her. So I told her that I did. So we're dating now. And as much as I didn't think I'd like it, I love it. I think the reason I was so against it is because I am still getting over Chloe. After all, today is the day I was supposed to get married.
But as to the crazy people, today I was texting Chloe's old roommate who wants to make out with me and I told her that I am dating someone now. Her response was

This is a good thing to know because I could've loved you as more than a friend, but now I know we're not supposed to be.

Now bear in mind I've never taken this girl on a date and yet she is saying crap about us and being together. I'm not going to lie, it was weird. Here are a couple other texts she sent me.

My love for you will never waver. I'm your friend forever and I still can't wait to see you. I'm happy for your happiness.

Question- you're not going to treat me weird/differently because I realized I could have truly loved u, are u?

I killed any feelings I could've had for you today, so there's no reason to treat me differently.

I'm not going to lie, this whole deal is weird for me. I mean the only time this girl was ever around me was when I was with her roommate Chloe who I was engaged to. I'm not really sure what causes people to be all sorts of crazy like that but it was weird. Talk about creepy
