Should I be concerned

I’ve been talking to this guys for 3 months and idk why it’s been that long bc I know for sure I want to be with him but idk if he feels the same way or not 🙄 the other day he told me he loved me and i was shook. I want to be with him but it was hard for me to say I love you too. But we were talking ab something and then he brought up this bitches name out of nowhere 🤨 not to mention I heard him in a video talking ab someone who cock blocked him and then he goes “so when we got in the room” and the video ended. The girl he brought up I knew well. I don’t have a problem with her I just know that she’s the real flirty type. So now I’m just damn confused. First you said you loved me, brought up this bitch’s name out of no where like changed the subject completely, and now someone’s cock blocking you? Like wassup just let me know bc I’ve caught feelings😂
