Me: You should come out this week. It'd be great to hang out again. 6:08 PM

HB: Ok I just started grad school so I've been crazy busy 7:15 PM

Me: You busy this Thursday? 10:03 PM

HB: What happened to that other girl u were seeing? I really don't want to be intrusive 7:20 AM

HB: Not that I'm saying I like u or anything just don't want to make anyone mad 7:21 AM

I woke up to that on my phone. We'd been talking maybe once every 3 or 4 weeks for the last 3 months. I never made a move, but never closed the door. Last night I was bored and decided to go for it.. I don't even remember exactly what she looks like other than the > side of HB.

Anyhow, my text game is very rusty (see above). What would be the best way to respond to this?

Specific answers are great, but generic ones will help me relearn.
