Only women answer: how to make female friends as a girl?

i have always wanted female friend group. i don't have any sister my age and my childhood was kinda lonely. then i entered colllege and live in the hostel.

i'm always sweet with my female friends and honest too. i have been very genuine always. but haven't felt "prioritised" over guy friends and in general. they have had a tinge of jealousy for some reason. i'm an outgoing sort of person and get along with people well, but my friends have always been wary of including me in their group. i even got to know that my roommate made sure that i wasn't included even when the other girls in her group wanted me to be there. what can i do to fix this?
