Am I overthinking this or am I right to be concerned?

Anonymous

I have been dating this guy for 8 months and have known him for a little over that. We have a friend who I am going to call Amelia for this. We met her through a mutual friend just before we started dating. The only issue there has ever been with her was at the start of our relationship when my partner saw her as a threat to our relationship because he thought that me and Amelia liked each other which wasn’t the case and I made that clear.

Fast forward to a few weeks ago and things have changed between us three. I am still with my partner however Amelia’s behaviour has changed slightly. As I mentioned, I spent free periods with her and we all used to hang out together. Don’t get me wrong, I understand hanging out with other people, but this is where things started to get weird. She stopped hanging out with me and hanging out with other people and my partner exclusively. She hardly hangs out with me anymore. When it’s all three of us, she doesn’t really talk to me anymore and just goes on her phone but puts it down when I leave.

Things started to get weirder when she said to my partner that he needed to meet her friend Lucy (also not her name), I have heard this friend mentioned once or twice and I’m pretty sure they are pretty good friends. When he said no and asked why she got funny with him. A little bit after this happened, I gave it some thought with my “teenage girl brain” and realised that the only reason a girl would do that sort of thing would be to introduce this person to my friend because my friend liked them or because I liked them, my partner and I talked about this briefly and at the time couldn’t work out why she had said that.

We are on summer holidays now, and Amelia hasn’t messaged me, we had a brief conversation when I asked her for a link and that was it however her and my partner talk a lot, he told me this. I got him a hoodie for his birthday yesterday and after he said thank you and stuff, the first thing he did was send her a photo (TBC)

I know guys and girls can just be friends, but this just doesn’t feel right to me. Another thing I feel is worth mentioning is the private snapchat story she has. She never posts on there however she did post a tiktok on there of a trend where you name a characteristic you like, something like that and she posted one about facial hair. My partner happens to have facial hair which at first I was like it's just a video

but I later realised that none of the guys she has shown me or talked about liking in the past have had facial hair so that seemed a bit strange. But like the title suggests, am I overthinking this or am I right to be concerned?
