Ugh drama! need help fixing it?

where i live there r a tonnn of kids. and we were all good friends up until this summer. me and a few others that are even closer friends made a little group (bad idea) and people felt excluded. we ended it. its done. its over. and for the most part everyone was friends again. but recently the group that felt excluded is treating us like crap. we apologized and they forgave us and we admit the group was dumb but now they r using that "group" we once had as an excuse to treat us badly. and me and this other girl are treated even worse because we r girls and sum of the guys seem ist to me. for example, they all invited us to go on a bikeride. once we cought up to them they all fled away like a joke and avoided us then yelled at us wen we said we didnt wanna play a game. how can i get everyone to b friends again? i tried being nice and that didnt work. i tried just avoiding the kids that are dissing us and yet they still find a way to make me upset. and i cant just leave cuz we all live within a few blocks! plz help :(
