<human>: Can you provide a brief rundown of the text in within 3 sentences?

This girl and I have been friends for about two and a half years now, but were never particularly close until recently. From January to August of this year, she was dating a member of our group of friends. She's said that she wasn't particularly interested in him, but was pressured into it by our friends, who thought the relationship would be good for them (or at least him; he was rather depressed at this point in time).

She broke up with him in August, and almost immediately after, she started talking to me outside of the time already spent together around campus. The more we talked, the more I realized I was attracted to her and the more I realized she had been attracted to me for some time, including while she was dating the other guy. And for the last month and a half, we've been dating.

What bothers me though, is that the reasons she gave for breaking up with the other guy are exactly how she acts towards me. He expressed a fear of being hurt by her, which she has expressed to me. She felt he said "I love you" too early into their relationship, but she's expressed that feeling to me even earlier in ours. He acted possessive, and she says things like "you belong to me." He was thinking too far into the future, and she's made comments about being together years from now. She felt pressured into having sex with him, and I feel myself getting to that point very soon.

Admittedly, this is my first relationship. I've said I love her, but honestly, I'm not sure what that means. I like her. I like her an outrageous (to me, at least) amount. There isn't a single thing about her I don't like. But how she acts is... troubling. I don't see it heading anywhere good. I haven't mentioned my concerns about this to her, and I know I should, but it'd hard bringing myself to ask her. Why would she act this way when it's exactly why she broke up with her last boyfriend?
<bot>: My girlfriend of a month and a half (and friend of two and a half years) is acting the same way her ex-boyfriend did, which is why she broke up with him.
