Are these signs my longterm boyfriend is cheating?

*wont keep me as his wallpaper; doesn't let me tag along with his friends even though i hardly ever see him anymore; picks fights; has no sympathy to my emotions; doesnt mention me on his facebook statuses anymore; wont hang out at normal times; constantly cancels when we do have plans; doesnt take me out anymore; doesnt pursure the relationship anymore; wont let me see his phone; normal calling patterns have changed; tries to rush through sex; always has other plans; constant calls and text from other people; playfully jokes about doing things with other girls; makes intricate lock patters on his phone knowing that i always forget how to do it; flips out if i try to answer his phone; doesnt want me to visit him at work; and i just get that feeling! We always had problems but i never suspected cheating before but this feeling i am getting is so strong!
