How would you have taken this text message?

Okay, so I've been wondering about this. Me and my ex girlfriend almost dated for 9 months. She broke up with me about 2 weeks ago saying she couldn't think of me as more than a friend, which is fine with me. I figured it was coming after she ignored me for almost two weeks, so I wasn't really surprised. Just a little hurt I guess. Now after we broke up and I got back home I sent her a text message saying "thanks for everything!" At the time I sent this because I wanted to let her know that I appreciated the time we spent together and all that good stuff and to let her know there we're know hard feelings. We decided to still be friends also. Though later I realized that she might of thought I was being smart, but it wasn't my intention at all. I mean age never responded back, but I thought maybe she might've been hurt too and didn't want to talk or whatever. Now I saw her a couple days ago and I did say hi. She sorta just waved and we never talked directly. We go to a small group for church every week. I was going to talk to her after, but she just left. So I don't really know if she's kinda ignoring me now or just doesn't wanna talk. I'm not really upset, I just don't like it when people are mad at me for no reason. Of course I may be overthinking it, which probably is the case. Anyways I wanna know how you guys would have taken my text, thanks!
