Will a guys long time friend who is a girl get jealous over a new girlfriend?

My boyfriend and his friend have been friends for 25 years roughly. She is a big girl with a burly bitchy attitude. I am not overly fond of her but have never expressed so. In the beginning when we were beginning to date she was around a lot and stayed the night in the guest room every so often. She also had him doing a lot of stuff for her. Well now I’m on the picture and he bails on hanging out with her and his other mutual friend of theirs. She doesn’t make me feel super welcomed, sometimes act like I’m not even there when she comes around. My boyfriend always gives me extra love when she does come over so I don’t feel left out. Also found out a few days ago she is now hanging out with his ex wife who she hates and he finds this weird. She also was asking if I was with him that night and he told her yea. He said he didn’t know why she even asked cause she was welcome to still come over. She has never called me by my name ever. Just called me his girl friend. I see her a lot less than I did cause most of the time he is with me and she only comes around if I’m not there or for a few seconds. His other friend a gay guy has been very welcoming and warm to me. Her definitely not so much. Is she jealous of me?

I should note there is no romantic feelings towards her on his side. And as far as I am aware they have always been platonic
