Girlfriend seems a bit too busy with social media than to do stuff together sometimes... and usually about one person, advice?

My girlfriend seems busy on social media a lot to actually do stuff sometimes... and she says her Instagram posts come up randomly so unless she looks at something for a while it doesn't pop up. We went away for Christmas to see her family and hardly had any time together, when we came back. We spoke in the past about a guy in a local band that she used to know as they were friends in uni and she likes and I mean likes every one of his posts without fail... its constant even after a post 2 days later where he just posts a 20 second video of playing drums. However she doesn't do this with any other people... I wasn't exactly happy with it but hey its just a like. But then the weekend after we get back and spent 2 weeks at her parents so didn't really have time together, she is on social media again, she has liked his new post while we are sat down watching something together... fast forward and she has to go for a funeral, told me she was too busy most of the time with her family to message etc. But I've seen she wasn't too busy at times... as while she was there she liked another post of his and one of his band a few times later... no other likes on any other people, posts or pictures... should I bring it up? Am I overreacting? I feel like I was messaging her to be there for her and she cared more about his posts/messages...
