<human>: Last night I was texting my ex-girlfriend, and she was telling me about how a friend of her's got engaged. Then out of the the blue she texts "If you would've proposed to me I would've said yes". I was completely caught off guard by the statement and did my best to respond to her in a way that accurately represented where I was emotionally since we are not dating. I told her that while I saw a future with her while we were dating, that I felt that even now I am still too young to be considering marriage.

I think the biggest difference between her and I, and maybe this is a flaw with myself, is that I'm not going into a relationship thinking that this person will be the person I marry. Nor am I during the relationship thinking about the plan for when/if I will be proposing to someone. All I look for is someone I'm comfortable with and have fun with and if it became that then great.

I just got completely caught off guard and I am trying to figure out where that came from and how to act around her now.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Ex-GF said that if I would've proposed to her she would've said yes. I didn't know how to respond really and tried best I could. Things are awkward now.
