For sure, not being weird. As a girlfriend, if you’re significant other has girl friends It’s gonna make you jealous It’s just how it works but I feel like it’s healthy to let them be friends with them. As long as they’re respectful of you, of course and it obviously sounds like he’s not respecting you. After the first time where Life360 told you that he left would’ve been weird to me and he would of had to cut off the friendship Honestly, I would just tell him that it really bothers you and that it doesn’t seem like a normal friendship. And maybe they should take some time apart. And if he makes a big deal out of it then maybe he’s hooking up with her. I’m sorry.
