So I got the girl I was texting for forever, we fucked, then we went on a date half a week later.

Since then she has been busy.

The sex wasn't really good (her condoms didn't work for me, and I forgot my own).

Have I just lost her forever? She's been texting me (initiating still) when I don't respond for a couple of days, but we went from 3 dates in a week to absolutely no contact for two weeks? At this point it just seems like she's stringing me along (though I suppose it's possible she's just busy).

I asked her what her schedule was like this week, she gave an excuse of having to do a billion things.

I replied with, "ok then" and don't intend to text again.

Am I right on that course of action?

Sucks, because I sorta liked this one. Even if my sexual compatibility is WAY better with this other girl I'm hanging out with.

Oh well, either way, date with a hotter girl on Sunday.

I think you answered your own question. Move on. Or you could give it one last try with "Look, I enjoyed hanging out with you and I think we had a good connection. Let's meet this Saturday (or whenever)." Complete honesty. Stop playing these stupid little games and go for it fully now.
