Bf says this? What’s the intent and is it normal😅

My bf and I have been together for almost a year and a half and we’ve hit a rly rough patch especially with him moving some distance away. He mentioned that this girl he’s pledging with in a co-ed frat had Arie flare leggings and that they looked rlly good and that she’s rlly good at posing for photos like a model (but he’s been telling me about this one gal a lot recently) and that I should get a pair too. I know she’s his type and I already own a pair of flare leggings and he knows that so I’m kinda confused why. He knows I have a lot of body dysmorphia issues and to me it’s Kinda odd that he’s checkin out other girls but maybe that’s an extra insecure me from our relationship flying downhill currently. Is his intent bad and is it normal
