is this weird?

so this is a long story that goes back about 4 years. so I’m in this relationship with this guy and his friend group used to be super close one of them being a girl. but then he stopped being friends with some of them including the girl and I ended up being friends with this girl, and she would tell me how close she was with my boyfriend like how she would text him when she was sad and only they would go for rides and he would sing songs with her in the car and get food with her and I never brought this up to him because it was so long ago and they aren’t close anymore but he never told me about this stuff when they were close so I feel like it’s weird.. now a year or two passes and we’re both not friends with this girl anymore and I hear his brother say how this girl got him a really nice christmas gift that he wanted around the same time we all stopped being friends and I didn’t know she got it for him I feel like he should’ve told me. idk but now i’m just thinking about it and I remember him saying his parents got it for him at the time so why lie about it. also they were all so close that his mom still invites her over and hangs out with her. like i get they were really close but it low key hurts that his mom wants her around. am I being stupid or is that weird that he never told me these things? it has been years so I probably won’t bring it up now but I feel like it’s really bugging me right now so I just need to know if i’m being crazy or not😂
