Need advice

I started a new job where I'm away from my boyfriend for 9+ hours. We haven't had any time together. He went to a work party at a bar on st Patty's day and was out for 8 hours. I had a head ache and missed him so yeah I texted him and he got irritated at me. I was upset that he was out so late and so long which he wasn't sensitive to. His Co worker that hits on him invited him and his brother (later me as an after thought) to her party but I bailed because I was depressed. He still went and it hurt my feelings. I just miss him and he can't seem to find a moment for me. Sorry there's no question I have I'm just tired and hurting and lonely.
