She’s becoming a problem

Might be a bit of a long post. But my boyfriend and I are 19. We live together and have been together for a year and 4 months. He made a new friend two months ago and she’s starting to cause issues and I want to say something to her politely, but I want to make sure my boyfriends okay with it first. First off, when they started being friends they wanted to hang out and my boyfriend won’t hang out with a female without me by his own choice. But during this time, we’ve been in quarantine and he mentioned to her that he wants her to come to our apartment because he wants me here. She kept trying to get him to go to her house because she was apparently scared to leave the house (not due to covid, but she didn’t want to get in trouble and pulled over, which our PD announced they wouldn’t be pulling anyone over even after the “curfew” they set). That was kind of my first red flag, just made it seem like she didn’t want me to be around.

Second, they talk on snapchat mostly, because that’s how my boyfriend communicates with all his friends. I admit, my boyfriend and I go through each other’s phone occasionally, but we haven’t in months now. She had asked if we did that and he said we did. They have chats turned on so they delete after 24 hours. If she doesn’t want me to see something, she turns it off so all the messages delete. Luckily my boyfriend is very open and he tells me all of this. But he told me he had no clue what she didn’t want me to see.

Third. They were talking on the phone and my boyfriend always has his phone on speaker no matter who he’s talking to, we were in bed just on our phones. Him being right next to me, I heard the conversation. She started explaining that she has no friends and that she’s picky about who she considers a friend. Basically she doesn’t consider my boyfriend her friend, but I don’t remember the reasoning.

Fourth and last, she was talking about something she wanted to buy from sephora (she still has a job and makes her own money, she doesn’t pay bills). She was talking about how expensive it was and my boyfriend having extra money, offered to get it for her from amazon for cheaper. The conversation went on and off as he was at work, but she later asked if he was really going to buy it for her. He said he was going to ask me first. She said that it was his money, so he shouldn’t have to ask me because I don’t control the money he makes. Which I’m not disagreeing with at all. I never ask him to buy something for me or take his money. I don’t like anyone using money on me. But my boyfriend and I just feel that’s the respectful thing to do in a relationship, especially as we’re living together, have our bills to pay and saving for another car. If we were to buy anything for anyone, especially another friend of the opposite sex, we ask each other just so we’re being open, honest and respectful of each other. She also had said that he shouldn’t say he’ll do something unless he’s really going to do it because he got her hopes up. She made him feel bad and really awkward. She knows I’m a little sketched out with her so she said “well that’s going to be a no then”.

He especially wanted to ask me with her because he knows I’ve had issues with her. He wants to keep me in the loop of their friendship.

I’m honestly just worried about her using him at this point. I would never tell him he can’t be friends with someone, but should I at least try and point out how this is all seeming to me right now?

She’s been blowing him off a lot lately and after he said he might be able to get the stuff from sephora for her, she got interested in having an actual conversation at that point. He tries to facetime her, tries to play xbox and usually either opens his message and ignores it till he texts the next day or just says maybe later and ignores him after that.

Sorry for the long post. But he’s really happy to have a new “friend” he can talk to because his other friends have been leaving him behind lately. I don’t want to ruin it for him but it just seems really odd on her part
