Tangled Up In Boyfriend Blues

So, like, I'm 23 and my boyfriend is 31. We were actually supposed to chill today because it was his day off from work, but I had to go to my cousin's wedding instead. My boyfriend got all mad though and started saying I spend too much time with family or something. He's been really suspicious lately-cussing at me and accusing me of cheating, wich is totally out of character for him. I mean, it's just a wedding, you know? Anyway, whenever I'm out of town these days, he wants me to send pics like every hour on the hour, and it feels kinda suffcoating. What do you all think-I should talk tings through with him or try to give us some space?
