what should I do?

Emilie • I need a friend
So a few days ago I had broken up with my boyfriend of almost 1 year Bc of something incredibly stupid. But now his friends girlfriend and her friends are talking about me and saying that I don't love him and they're saying that's why I broke up with him ( we are together now.) but he tells me to ignore them Bc they don't know anything about our relationship; but it really bugs me Bc ive never talked to these girls a day in my life. I just don't know what to do lol
