Ex advice

My ex and I broke up over two months ago, and about a month in we had a nice convo that left the door open and we hugged whatever, prior to that it was pretty much no contact. Over the past two weeks, she’s started initiating a bunch more but only to get our dogs together to play, nothing in any type of an intimate setting. She did however ask for my help when she was really sick and I took care of her a bit. She started texting me again out of the blue a couple times a week, and we were seeing each other with the dogs about every other day. Fast forward to Friday, she texts me out of the blue, we chat, convo dies naturally, and with a bit of liquid courage I asked her to grab a drink. Radio silence since. Am I wasting my time here? I genuinely would’ve been cool with a “no” or a “not yet” but ghosting me after all that seems pretty ridiculous and is very much under my skin. Im a pretty straight up guy and emotional games are not my thing. Part of me wants to follow up with her but I don’t want to make it more awkward. Any and all thoughts on how to proceed are appreciated
