6 Bridesmaids and flower girl and no groomsmen

HELP ... Our wedding was supposed to be a small casual wedding has turned into a big stressful nightmare... When we got engaged I got excited and went overboard and invited 6 girls to be bridesmaids (including his 2 sisters) Our wedding will be in northern Ca and my fiancé is from Ohio so his guests have turned out to be only his parents, 2 sisters, and one sisters family and the remaining guests are about 30 of my friends and family most of whom he’s never met. As if I don’t already feel bad enough about most of the guests being people he doesn’t even know, none of his male friends or family are coming out so all will have on his side is his 5 year old son and I will have my daughter and six bridesmaids including his 2 sisters. We are wracking our brains trying to figure out how this arrangement will work when we are standing up at the ceremony and it’s become such a sore subject since he’s so upset I invited so many bridesmaids that he won’t even talk about it with me anymore and just says do whatever I want. All we can think of is to add my friend’s husband my uncle and his dad... but he says he didn’t want to just add “filler” people to be groomsmen. Please help with advice on how I can fix this situation! The only ideas I can think of are have his sisters on his side but that would still leave 5 girls on my side. Or the other idea is have to everyone walk up but then sit down in the front row but I feel bad because a lot of the bridesmaids are traveling long distances and they have all bough special dresses. Pleeeasse Helllllp!
