Was I right to cut off my ex who wanted to be ‘just friends’ but got jealous?

This girl I used to date wanted to be platonic friends, we were for a while but I gave our other friend a gift a girl. ( the girl I used to date got jealous when she found out).

do you think I did the right thing by cutting her off friendship wise. she States that she didn’t have feeling for me anymore, but why would she get jealous?
