I [30M] have a pre-booked holiday with my family for 10 days. My girlfriend [31F] had booked one at the same time with her gay friend [31M] who was visiting from abroad who she has known for 10 years. Most of my holiday she has been busy with him and not made time to contact me. I have been seeing her posts on social media and feeling lonely and missing her. She has gone home and he has gone back to his original home too and now she is sad. I feel like I am pushing down my emotions, watching her enjoy herself on holiday and not getting much back. I understand I might be being needy here, but I might also be just being me. I'm confused how I should feel.

I've been struggling to enjoy myself because of how much I miss her and now she's upset about missing her friend and I've had to leave my feelings out of the conversation because it pissed her off a bit that I was upset at her for not making more time for me and concentrating on her friend.

She's always busier than me and I don't have many other friends so this might be skewing how I feel. I'm also very anti-social media use and a slower type of person than her (but I never tell her what to do or how to live her life). Basically, I want to enjoy my holiday apart from her but I miss her a lot and the fact she's not made time for me has really upset me. To top it off she's more upset missing her long term friend than me. What can I do? Are there fundamental differences in our personality and am I too attached to her? I know she loves me but we do it in such different ways.
