Groomsmen drama

Long post im so sorry... Not using thier real names.

One of my FH closest friends Bill is in our wedding. We got engaged like 2 years ago and he knew he would be in it and said yes to it. This is the 2 time bill brought up about he might not have enough money to get the vest. (The guys are dressing very casual. Only fancy thing they need is a vest and tie which we are looking now to see where would be the cheapest.)
Bill also brought up about is wife sally not being in it. (I have enough girls in the wedding plus i am not really close with sally.) Bill was saying he was hoping to walk down the with Sally. Even though he was fine whenever I originally asked him and he knew she was not in it. Bill also asked my FH if something happens someone does not have enough money to get there things I need for the wedding if we would ever talk to them again. My FH told him no because he doesn't want him to think it is okay to do this whenever he had plenty enough time to save up money. I feel like all this drama started after the fact she knew she was not in the wedding.

A little more back story about Sally she knew that she was not in the wedding like I said. But she assumed that she would be a backup if someone would ever back out girl wise she should be the one to take their place. First of all I never said anything about anybody being a backup second I never even told her about being a backup. I'm not even worried about any of the girls because all the girls that I picked I know for a fact they will not back out or screw me over. Whenever I finally told her that she was not a backup she freaked out and deleted me and acted like a child. The reason why I came out and told her was because she messaged me and said that she was going to buy a dress and the shoes that my bridesmaids will be wearing so just in case someone backs out she has all that stuff ready. I told her don't buy anything because no one's going to back out first of all and second of all I don't want somebody just going to the wedding having the same dress and the same look as my bridal party.

I am over this completely and I want to know if I should give this groomsmen One More Chance and if you brings out the situation again I'm telling him he's done or if I should just do it now. I really don't want this added on stress on top of everything else. We dont want to ruin this friendship either bc him And my FH are really close. I know some of you would say don't worry about it one less person to worry about but I am always a planner and I always need to make sure everything is in place at least some of it.
