1 week no text back, should I text them? (UW)

[sociallyinept]

It's been 1 week since I visited a house I like.

I thought it went ok at the very least. I could've been more social.

But I haven't heard back even though they said they'd text me back.
Is this a silent rejection or can I go ahead and hit them back up and say

"Hey (rush chair) I had a good time seeing the house last week and am still really interested in the house. I was wondering if there were any events I could come to in order to meet the guys"
