My boyfriends bestfriend

Kelsey • 21 years old and single
So my boyfriend is going to school, doesn't have steady a job but works as a ranch hand whenever they need him and has a lot of money saved up from when he worked on the rig in the past and pays his own bills. His best friend works on the rig and is here for two weeks and gone for two weeks. When his best friend is gone for two weeks, me and him spend every day together. When his best friend is here, I hardly ever see him or hear from him for two weeks. It's the only guy he hangs out with so I understand him wanting to spend time with him. But at the same time, he makes me feel like I'm put on the back burner. He doesn't make any set in stone plans with me while his buddy is in just in case they are doing something. It's Saturday today and I haven't seen him since Monday. And I won't see him until Sunday. And it's harder for me to see him because I'm going to college full time and working but on my days off I want to see him but can't because he's with his buddy. I don't want to be told to break up with him because ultimately that's my decision. So save your breath if that's what you're going to say and I don't mean that rude, but that's not what I need. That's a decision I have to make on my own. But any advice would help. I try talking to him but it gets blown off. We've been together two years in January. I try to be understanding since that is the only person he hangs out with but its hard when at times, I feel like he doesn't bother to see me. I feel like we are so much better when I don't say anything but then after a couple days, it eats me alive and I have to say something. Help! Advice!
