<human>: Can you condense the text into a few key points?

We've been sleeping together whenever we see each other (4 times in about 6 months) and just started to make the effort to actually go see each other of a weekend (5 hour drive).
I really like her but a it's usually about a month between seeing each other. We text in between fairly regularly but is it really enough? I can't lock in a relationship but I'm scared to live as though I'm single, because of how she'd feel but also what other girls I meet might think.
I don't want to ask because maybe she'll feel pressured into it, or the opposite and she'll think all I want to do is sleep around.

Sounds a bit pathetic rereading but oh well.
<bot>: I'm not sure if you can just have a "dating" phase from afar, and because it's from afar it tends to be extended.
