Search Results: start conversations with girls at parties

I'm mostly after what girls think of this, but feel free to comment too guys, no need to segregate :P

For instance,
Suppose you and a guy hit it off really well in person, to the point that you're happy to let him know about your plans for the future, your personal thoughts on dating and marriage etc.
In an instance like this, would you place more emphasis on what happens when you see the other person (catching up, hanging out, going to parties etc.) or the conversations you have via text.

Reason:
This girl and I have really excellent chemistry and have been good friends for about 4 years. I've always sort of gotten the vibe she likes me and I like her a lot. Neither of us has ever specifically said something about it to the other though. When we hang out, we get on really well. She smiles and laughs a lot, makes eye contact and is engaged in the conversations we have. Just recently we were talking and she started asking me about my future plans and, when I returned the question to her after answering, she told me about her goals and future plans and that she doesn't want to get married for approx. 4 years.

First off, what type of guy friend would you tell stuff like this too?

Secondly, when we hang out (even at parties), we mostly talk to each other and get on really well. However, she's terrible at returning my text messages. When she does, however, it is often with a thought-out, lengthy reply. But it can take her days sometimes, if she even replies at all. She is also a VERY busy person. A few others I've talked to have said she isn't the best at texting and they have similar experiences with her.

So my second question: is it likely that she simply places more emphasis on face-to-face communication than she does messaging and I am simply overthinking things? Or is it a sign that she just isn't that into me?

Thanks girls, I really appreciate your responses. This has been driving me a
