Not Spending enough time with bf

Lately my bf and I haven’t spent much time together in person. We’re both in college and work and very busy but every time I bring up spending time together, I get hit with “I have a lot to do I can’t”. Yet he’s gone paint-balling, he’s going to a wedding, and on a trip to Catalina island!!! He has time for all these other activities but not to hang out with me (I am unable to accompany him on these trips). It’s been almost a month since we’ve seen each other. I want to have sex too. I’m just feeling so disappointed. We FaceTime, text, and talk on the phone but I’m tired of feeling like I’m in a long distance relationship.
