Keep The Friendship or Move On ( bridesmaids drama)

I have been engaged since Nov 2017 and My wedding is August 17 2019 ( woohoo). My Bridal Party was 5 max . These ladies are long friendship and my favorite aunt . I have only one meeting with the girls so far the next one is Jan 19th which is ordering the girls dresses, My ladies have been supportive checking in or asking for updates. I have been very easy going so far. I have one bridesmaid that been very silent with this process. I had a talk with her back in march wondering if we are friends or associates . We hang out in a group since we were freshman in HS. She is very IT tech/Anime personality and told me she just wasn't girlie and doesn't know how to help. We spoke for two hours about everything . I just told her I know just check or help with Pinterest will work . She hasn't really said much even in group chat yet I see her board of wedding selection idea for her ( she just got in a relationship and not engaged). I was upset because one of the dresses was discontinued and she didn't even ask me was it hers. I told her she doesn't have to come jan 19th for the dresses. My MOH told me she usually ask her about the updates and questions on the dresses etc. MOH said she mentioned she can ask me as well. I just thought of it as being odd of asking her instead of me. I now know she has been trying to be involved but without talking to me (shes odd like that). Should I reach out to have a conversations or Just cut it off all together . MOH says don't lose the 10+ years friendship since we know her personality vs Mom/FH saying cut it off you can outgrown friendship.
