<human>: Provide a brief overview of the text.

so i am pretty active on social media (for my job) and so i will interact with people/friends/clients and my gf will get really mad over me liking a girl's selfie but i noticed that late at night, after we say goodnight to eachother on the phone, i will see that she spends time looking through pictures of guys' pictures. mostly models but sometimes guys that go to school near her.

i tend to get a little jealous so maybe thats y she does it at night when she thinks im sleeping, but the part that ticks me off is that when i look at the pictures she's liked, she will go back weeks into these guys' accounts. once she went back like 62 weeks into some dudes feed to like a selfie he took of himself in the bathroom. 

we all know that if someone likes a pic of you from over a year ago... she's wantin the D (lol) so it's obviously she's doing it to get the person's attention. im not quite sure how to bring it up to her as it usually ends up into an argument where she will walk away saying "im done talking about this." and im the one feeling like shit.
<bot>: gf gets mad when i like a friend/client's selfie but she will go a year into a dude's instagram feed to like a half naked selfie, how do i react to this?
