I'm unhappy&ive been married only 3 weeks.My husband nags all the time&last nite he took his wedding ring off?

I have been married for 3 weeks and I feel so unhappy! My husband has became a consistant nag but NEVER was like this until we got married! I love him but I'm scared that this is what life will be with him. He has his faults as do I but we solved the majority of big issues before we got married and now I feel like well what the hell is this! He called me a name yesterday and we have dealt with name calling months ago and have been doing great until yesterday. So I'm uneasy thinking that it may be an issue again. I tell him to stop complaining and nagging everyday about stupid things because it's effecting me. I don't want a divorce but I'm at the point that I keep talking to him and nothing is changing. I want to be a good wife but its like whats the point if my husband is still acting as if we are bf & gf! I just want to be a happy newlywed couple but I don't enjoy even talking about our wedding when people ask because then all I think about is how my husband is towards me now.Yesterday he asked if I wanted to go to his friend's son's 3yr old bday party. I told him maybe but after I came home from the gym I was tired and told him and my stepson to go without me and I'd take a quick nap and if everyone decides to do something after that to call me. Then later he texts me that everyone else wives is at the party, I didn't respond back. I just got dressed even though I was tired and went up there. When I arrived the kids had played, finished their pizza and all that was left was to sing happy birthday, eat cake, and open presents. Everyone was happy to see me BUT my husband. He complained that I missed watching the kids play, etc. I told him that hey I'm here now for you let's enjoy the rest of the party. Then two mins later he complains that he told everyone that I was busy at home and then with me showing up at the end made him look stupid! It that point I just felt so frustated that I said well do you me to go bc you bitched that I wasnt here and now that Im here youre still nagging. He called my buff and I left. My sister-in-law sent me a text saying that everyone was now headed to MY HOUSE! So I had to put on a "wifely" face for all 15-20 members of his family coming unexpectedly (to me) to our house. My husband arrived first with such a ugly attitude. I told him to just leave me alone and not to talk me and that's when he called me the name. I used to get so upset and blow up on him but I just went into my room. he text me that he was going to let 4 of his nephews stay the nite. After his friends and family's kids started to get unruly bc most of the adults were socializing and not really caring if they tear up stuff I just got fed up with everything and left and had dinner with my friend (girl). Then around 11pm my mother in law calls me to check on me and informs me that my husband didnt watch the boys and in fact he dropped his son off at her house so he could go out! I got home around 12:30 my husband got in after 4am. He slept on the couch. Then this morning he left out. My sister in law had everyone at her house to watch the game. I stayed home. At this time my husband and I still havent talked. So I decided to text him how I was feeling about everything and then I called him and told him that I needed to talk. He said that he didnt want to talk tonite maybe tomorrow. I just hung up. After 20 mins later he and my stepson came home. A few hours ago I was cleaning up the bathroom and seen that he left his wedding ring. Idk if he had if off last night or took it off this morning but my point is it was off. Shortly after I found it I just wanted to scream at him but I just left to my moms instead. I have no idea what to do!!! I am trying so hard but its like Im getting nothing back at this point! It was just Friday morning that he was telling me how lucky and happy he was that I was his wife and then all of this! I dont want to think about a divorce but this cant be what marriage is especially only 3 weeks into it!!!! Any sound advice???
