Stuck!!!

There’s seemingly nothing wrong with my relationship, except that I feel like I’m getting bored. I hate the feeling but I can’t help it. We haven’t said we love each other yet, he doesn’t really ever express feelings, we pretty much only have sex when he drinks, don’t see each other much now because if his job. I just really don’t know what to do. I value the relationship but I don’t want to drag it on if it won’t work. Anyone had a similar situation? Advice or encouragement?

For reference we’re both 20, juniors in college
