Is my boyfriend dragging me along or am I being a dumb girl?

[confused]

It's been almost 10 months that I've been seeing my boyfriend. I've never been one to care about jealousy and I never had suspicions until he started keeping his phone out of my sight and would answer texts only when I left the room. So I got suspicious. I snooped for the first time in any of my relationships. I caught him talking to other girls on Messenger, dirty bad inappropriate things, and he always keeps his phone hidden and keeps a password on everything now. He just started to be so sneaky. I forgave him when he apologized and moved past it, whatever. Recently I asked him to put his profile as "In a relationship" with me and he says he doesn't want his life on Facebook. He won't talk to me at the end of the day when I really need to talk, and he legit ignores my calls and texts when I need him most and tells me I'm being too nuts! I just want to talk to my boyfriend at the end of the day am I really nuts? What the hell?! I love him but I think I'm being dragged along as a convenient friend with benefits only? What do I do?
