<human>: Can you give me a shortened version of the text?

seeing for about 3 years (we are both 19) dumped me for what I think is the stupidest reason. I just dont get it. So she is crazy about all this social media, snapchat, instagram, facebook, and I honestly hate them all. The only reason I have them is to not look boring in her eyes though I rarely ever use them. I try to like her pictures when I see them cause I know its important to her and whatnot. So she posts these 3 pics last week that I never had a chance to see. And the other day I hop on and scroll through my feed and see this hot famous chicks picture, and I like it. And let me tell you guys I dont know how this girl found out but she did and flipped her lid when I didnt like her pics and liked another girls pic. I tried to explain I simply dont get on there as much as she does and didnt see them but she wasnt having it and dumped me. Okay I seriously dont know if im happier to have her crazy social media obsession out of my life...or more sad that shes gone!! I think this is just very immature. What do you guys think?!
<bot>: Girlfriend left me because I liked another girls picture on instagram and didnt like or see hers. Is this immature or is she in the right?
