<human>: Can you give me a shortened version of the text?

So I've been chatting with a guy on Tinder for a month or so, we'll call him Glenn. we're Facebook friends, and he texts me daily. We went out last weekend and had a beautiful time, it was fun, great chemistry (well now I'm second guessing that). We were out for hours, and ended up back at his where I stayed over. This was not planned, the night just kept going on until suddenly it was 2am and he invited me in for wine and to continue our conversation. We made out like teenagers and whilst we didn't have sex, there was plenty of grinding/dry humping whatever..

Anyway, all week he has been texting me, asking when to meet again, inviting me to spend time with him, even quickly seeing me on my lunch break (we work near each other) and then messaging me after to say how great it was to kiss me again...he seems like a great guy. Super attentive and positive, etc.

 Last night, I was having coffee with my friend Christina and her sister Amanda. I was telling them all about my date and showed them a photo of Glenn. Amanda immediately grabs her phone and shows me her having a conversation with Glenn, which is fine - I've only been on one date with the guy, he can talk to whoever he likes.  

The problem was what he said. The conversation went something like this:

Amanda: so, are you having much luck on tinder?

Glenn: there's heaps of fake profiles, I've only been on one date this past Saturday and she was pretty chunky. Wbu?

I'd like to point out that I'm 167cm and 57kg. 

Amanda immediately deleted him off tinder and I haven't said anything to him yet. He doesn't know her and I know each other as Amanda and I aren't Facebook friends (mostly because I don't see her that often, as she's older than my friend, her sister)

 I'm not sure if this is something I should confront him about, or what? What would you guys do? Is this a red flag/bad sign?
<bot>: dude I've been chatting with awhile and have recently gone on a date with refers to me as "chunky" to a girl he doesn't know I'm friends with.
