<human>: Give me the gist of the text in a nutshell

My boyfriend and I are both 25 years old, have been together for 2 years and 3 months, and were friends for 5 years before that. He lives 3 hours away by train because he is in business school and I am working. He is always going out after school to dinners, drinks, or night clubs. I work and come home and I don't have any friends where I live. Here are some things that have made me think something sketchy is happening. Please let me know if these are legitimite concerns or I am just being paranoid and insecure. (It is everything together, not just one event that makes me concerned.)
1) We have a texting app where I can tell if he is on his phone and he was but ignored my call because it went to voice mail after the second ring. I called back and it kept ringing. He called me 20 minutes later and told me he was discussing the bill at dinner.
2) After all this time he won't put "In a Relationship" on Facebook because he says he is a private person and doesn't want people knowing his private life. He does have an album with pictures of me, but that is it. And he doesn't like when I tag him in pictures of us. He calls it "clogging his wall".
3) When I visit him on the weekend he doesn't want to go out with his friends even though he goes out with them all week. I have only met them once in 3 months (I see him every weekend).
4) I saw him tagged on facebook in a picture at dinner with friends and there was a girl sitting next to him. The one time I met his friends, she was there and she said Hi to everyone except him.

If this is a bad relationship, I don't even think I could break up with him. I am terrible at ending things and I hate dating new people. But I feel like something is off in our relationship and for this reason I have just last week started being mean to him in an attempt for him to break up with me. I feel very insecure about our relationship. And I would like to know if I am the problem or it is him.
<bot>: My bf won't put in a relationship with me on facebook and doing other weird things, I am wondering if this is normal or if I am just being paranoid.
