I need an outside opinion on this

I need someone's opinion on this situation. So I met this girl a few months ago and we started hanging out and talking. After a few days she told me that she just had a baby that was six weeks old. No big deal I was just getting to know her and that wasn't a deal breaker. So we hung out for about three weeks. She became very clingy, or at least to clingy for me in that amount if time. During the time we talked I mentioned that I like to go out of state to football games with a few friends of mine and that I thought maybe we should go to one sometime. We didn't make plans or get rooms or tickets nothing like that, it was just mentioned. Bare with me here. Also about week three we went to dinner and she we talked a little about her daughter. She asked if it was wierd that she had a kid and I responded and said no, if you like someone then you also like their kid. Again there is no serious talk going on, remember this is only three weeks into it. I decided that even though she seemed like a good person that it just wasn't gonna work and told her just that. She was fine with that and everything was cool. Just went our separate ways. That was about two months ago. A week ago I got a message from her and she said " she wanted to talk to me about what happened with us" I was kinda in shock, I told her that there was really nothing to talk about it just wasn't what I wanted. I'll spare you the little argument and just tell you the last thing that I couldn't even respond to. She said " I think it was a dick move of you to talk about the future with me" I then said future? What are you talking about? She said" talking about going to football games with me and being in my daughters life, that's bullshit!" I had no idea what to even say to that. So here is my question I didn't think that merely talking about things meant that they were gonna happen. Am I in the wrong? Should I just not talk to new dates about anything but the weather??? Also her sister, who I have never met messaged me a day after she did and said that I at should talk to her and at least give her closure... WTF. I am trying not to be a dick but this just seems wierd to me. Any comments greatly appreciated! Thank you!

I agree with you on this one. Mentioning a football game isnt exactly discussing your future plans together. I dont have a clue what she was thinking
