Hello all! Throwaway because I don't want my family to see this.

So I'm getting married sometime in the next two years, very new engagement, but I've been thinking of who I want to be my bridesmaids. I have my sister and my good friends from high school, but in order to match my fiance's number of groomsmen I need one more girl. 

My cousin who I have known my whole life and have been fairly close to has been dating this awesome girl for about a year. Her and I get along super well and she's super fun to be around. I'd love for her to be in my wedding party, but I don't know if it would make things awkward with my cousin not being a groomsmen and him being the one I'm related to. I don't want to force anything or make anyone uncomfortable. I'm sure I could find someone else to fit into the wedding party who would fit just as good, but I just get along so well with my cousin's girlfriend I feel like she would be a great fit.
