<human>: Ok so I turn 27 today, I've been talking to this girl and we get along just fine. She wants to take it further but I'm just not positive that's a good idea.

I mean I like her, but she's 7 years younger than me for a start. She's really into me and although we haven't talked about this being serious I know that's what she wants and I do want a serious relationship, I'm just not sure that I want it to be with her. I just get the feeling things with this girl are going a bit fast and that she doesn't really comprehend what it is that I am, though we have talked it through as I am all for not hiding it from potential partners.

On top of this I have other prospects at the moment that I haven't had a chance to properly engage with, one of whom in particular I have quite a big soft spot for but that whole thing is progressing at a much slower pace. To the point I'm not entirely sure if it's really progressing at all.

So, thoughts? Do I get intimate with this girl cause it's what she wants? Do I tell her I can't be with her and break her heart?

Can you condense the text into a few key points?
<bot>: I go ahead and she potentially gets the wrong idea or I put on the brakes and potentially lose my only viable dating option.
