Girlfriend and I got into an argument won't get into details but I blocked her number and went to block her twitter a few hours later and seen she changed her picture to one that clearly is showing off her tits and she made her account private and followed 5 accounts probably some guys.

Anyways should I allow this behavior? She was a pretty good gf until recently where she started doing dumb shit during arguments similar to the case above. She always does her best to sexually please me and keep me happy but I don't know where to continue from this obviously it bothers me so I don't wanna accept her back thinking she can do it every time we argue, but we also have been together for a while so I don't know if I should next or what the fuck to do

Just need some hard advice right now to get me out of pussy mode thanks
