Need Boufriend advice

A few months ago I asked my bf to block a girl on Instagram because she was being too friendly. And today I logged into his snapchat and saw that after he blocked her on Instagram he went on snap and apologized to her WITH heart emojis and told her “ I’m sorry my gf made me block you “ and stuff like that. So now I’m hella pissed ams don’t know what to do. ADVICE PLEASE. (And also he’s following a bunch of girls that post their nudes and sex tapes ).
