I was dating a girl from mid Sept until the Wednesday before Thanksgiving. Everything was going well so I decided to introduce her to my friends the first weekend in Nov. I picked her up and we met up at a brewery in town (not a place you get wild). Everything is going well. My friends to like her and she seems to like them. We left since it was nearly closing time and went back to her apartment and watched a show. After that we were talking and I asked her what her expectations were with dating and (order may be off) said I'd like her to be my gf. She then told me she was previously engaged to a guy she dated from high school up until a year and a half ago. She dated him for 10 years+ since we're later 20's. She told me she'd definitely like to move things forward but not put a label on things which I said was okay. Before I left for the night I asked her if she'd like to come to a Friendsgiving and she said definitely with a huge smile. We were still texting and talked via phone a few times and things seemed okay for about a week then she starts to be weird. The day before Thanksgiving I get a text "You're a really run guy. I'm not as sure as I thought I was to start dating. I don't want to waste your time" 2hrs later I get "Hope I didn't upset you. Thought you should know" I message back "Things seemed off since you when home last weekend. Did something happen. I'm sure it was difficult to open up about being engaged last time we saw each other." What should I do?
