Search Results: wonder about the future

So I'm bisexual and I've been chatting to this girl for about 4-5 months now. We live in the same country but in different parts of the country and I've decided to go and meet her.

From day one, she was quite flirtatious. I've been honest early on that I'm into girls and when I felt she was flirting, I started flirting back.
We've had some really serious conversations via text where I've brought up things about us having kids together etc and she has responded. Whether she was playing or not, this is not something I believe a straight girl would do. She must be interested in my opinion. She's also not someone who strikes me as an asshole. Quite a wholesome person who has her head screwed on right.

My question though is around her interest. Often, she'll text first and I respond. Sometimes straight away or sometimes about 15 minutes later (no game. Just busy). With her, we'll text back and forth and then suddenly, she stops responding for hours, or even overnight. I find this bizarre. She is busy with other stuff but I'm wondering what's up with that. Like now, she texted me out of the blue and I responded 10 minutes later, I see her online on WhatsApp very quickly but she doesn't read my message. She is hardly ever online tbh which makes me think she doesn't want to come across as too interested as she may fear her attraction to me.
We Skype once a week and I've seen her visibly taken aback. Ok, it sounds silly but sometimes things do manifest on someone's face or by their mannerisms.

I am confused by her texting behaviour. As it stands, I'm due to fly up next week. She will say yes she will meet and we'll start discussing the future, in a roundabout way, then she pulls away again.

I know for a fact she is not seeing anyone else. As I said, this girl isn't an asshole.
