Is it normal for my boyfriend to be talking about other girls to his friends?

So basically my boyfriend and I had been dating for almost a year and one day I was on his phone (lol big mistake) as one of his friends replied to him on messenger and I noticed that they were talking about a girl that goes to his gym. The thing is is he randomly brought up the convo about her with his friend. This is how it went:

BF: “Hey! do you know Amy?”
Friend: “Yeah I know of her we used to work together, we aren’t really friends. Why?”
BF: “She goes to my gym, I just befriended her.”
Friend: “Oh cool yeah, her and all the girls that work at Kmart look like they’re out of some American teen movie ” (can’t remember rest)

AND

another time he started this convo;

BF: “I just saw your friend Amelia holy shit her hair is amazing wtf!”
Friend: “haha yeah she’s pretty hot”
BF: “What’s she like?”

So I saw these convos and freaked out and was so angry and confused why he was going behind my back talking about other girls. We talked about it and I just had to ignore it, but I can’t help but feel scared.
When I asked him why did he go out of his way to ask his friend about this chick and ask him what she’s like he just told me he was trying to make conversation with his friend and his friend is depressed and he was trying to get a convo going. Not a great excuse tbh.

He hasn’t given me reason to doubt him since then but I can’t seem to forget what I read.

What do you guys think? Am I just overreacting? Please help!
