Is this behavior normal? should i be worried?

My name is Jen and I've been in a relationship with the same guy for a little over two years. We met on Facebook. Always had mutual friends but never once met or hung out. One day I posted a status on Facebook he found amusing and he decided to comment on it. From there we were both stuck like glue.. We were always together as much as we could be. Me living at home with my mom she never really liked us being together a lot cause she was scared we were gonna have sex and I was gonna get pregnant. So, anytime we got together was very amazing for us both. I remember times were we'd get into small arguments and he used to cry because he was so scared to lose me. [I'm his first everything (Girlfriend, Sex partner, Kiss) ] some where between 8 months and 1Y/4M we started to argue a lot.. never anything too serious and we would always get over it after about an hour of being mad at each other.. Now we've been together two years and I've noticed a lot has changed with him that he doesn't seem to see. Around 1Y/8Months he started to be more distant.. not wanting to go out with me anymore (Such as: Movies, The Mall, Dinner) we used to do these things every weekend. I always ask if we can make plans but he always turns me down and claims its cause of money which I know for a fact is untrue because he will go out with his guy friends to watch super hero movies. I've also noticed lately that he refuses to cry over anything that happens between us.. he isn't scared to lose me anymore and now he will actually tell me to leave. He will say that he doesn't care and to pack everything I own and make sure I call my mom to come and get me. He's kicked me out a few times but we always seem to get back together. I also notice that when we are in public.. like going to Wal-Mart he won't hold my hand.. and when I grab his.. he usually either holds mine very loosely or pulls away. He doesn't think I notice.. but I do and he doesn't hold me when we're standing somewhere [ He used to put his arms around my waist if we were just standing in the middle of a store ] he doesn't do any of that anymore. He also has this bad habit of calling me names. [Bitch, Whore, Piece of shit, Stupid] & honestly, other than a small attitude I have with him.. I don't understand why I get called these things! Especially a whore because I'm a VERY loyal person and could never cheat on someone cause it's happened to me so many times. He doesn't want to lay down and watch movies and HE ABSOLUTELY HATES CUDDLING! He wasn't like that in our earlier relationship.. He's admitted to me once that he doesn't like cuddling cause it makes him think of everything we've been through? When we do get into small arguments I will ask him if he even wants to be with me because most of the time I'm amazed at the things he can say to me and he always says "Its not up to me.. you can decide things on your own" when I tell him I do want to be with him and I just want to know what he wants he calls me immature and says I'm not grown because I ask what he wants. Lately he's had this routine.. Wakes up, Eats, [goes to work if he has to] Plays video games until 6:00am and then sleeps till 3:00pm. He does this every single day. If I say anything to do about having some time together he goes insane and gets mad because he considers me sitting beside him while he's on his laptop and us talking when he's not too busy to listen spending time together.

Also, We broke up awhile ago for 5 days straight.. Within those five days he told me he didn't love me.. he wasn't EVER coming back, Relationships are too hard and I'm too annoying.. Then on the fifth day he took me to my job training and he said he wanted to get back together after I made a sexual joke towards him.

Today as of [10/23/13] he told me the only reason he got back with me was because I begged him.. Which I did a little but on the way home from job training I gave up because he denied me every time for four days straight.. & he said he was over me when we broke up but he still loved me which didn't make too much sense to me and made me think the only reason he brought me home was because he wanted sex..

Idk what to do anymore. any little thing I say to him sets him off and he turns hulk mode..

Is this normal behavior? Should I be scared? Break it off?

I NEED HELP.
I want to be with him but I don't know if it's such a good idea anymore.
