I need some advice, what do you think? (kind of long)?

Me & my Boyfriend have been going out for awhile. July19 will be exactly 1 year...my longest relationship yet. But lately , all we've been doing is arguing. He's just been getting on my nerves ALOT & i know he's been trying to be a good boyfriend...Here's the thing..This past month & month b4 i've notice it alot...He's Constantly wanting to touch , kiss & hugg all over me..just yesterday we were at the library & i was tryna find a book & he wouldnt let me thru w/o kissing him..he wasnt mean about he was just like.."u cant get thru without a kiss" i mean come on its the library. now if i dont kiss him, hug him or just sit there something is automatically wrong. Also, when we were walking yesterday i went home because i didnt feel like being out & he got pissed off because i didnt give him a hug. I personally hate PDA theres nothing wrong with hugs but he was just annoying me. when we first got together he had ALOT of friends now he doesnt chill with them because hes always up my ***. i was going to hang out with my best friend and he invited him self . i mean sometimes itll be okay but damn i wanna hang out with my friends alone sometimes because i see him ALL THE TIME. as soon as he gets off work he wants to come over and stay and if i tell him no sometimes hell be like well do you need your space...blah blah blah & its hard talking to him because hell cry so idk how to handle it. i love him so much but i just dont know. im the type of person where i can be okay just sitting in & reading a good book. Once i even told him he should treat me like his ex girlfriends just dont cheat on me...because he was a little player and wasnt up their *** 24/7. he also gets pissed off bc i try to hang out with my friends (that i hardly ever see) & i was gonna hang out with his one friend til he got off work and he made a big deal out of it...he was like well why yall gotta chill why cant we just pick him up when i get off work....When i do see my boyfriend he wants to MAKE OUT not HANG OUT & its just soo frustrating! Btw, He's 19 years old about to be 20 & im about to be 19....any advice other then breaking up with him bc i dont want that =/ thanks <3
