Help with my ex girlfriend

Hello,

I am new here so I hope this is in the right area.

So me and my gf broke up about two months ago, I did the whole begging pleading thing for about two weeks, and to no avail got shut down. So I started no contact. About a week after, she came over for a "late night" and she said it was only that and to not think anything of it. So after that night, I started no contact again.

Three weeks later, she had asked me twice if I was dating anyone new and had gotten jealous and mad at a couple of posts I made on instagram, when I was just out trying to lie my life. Two weeks after that, she had to come over and get the rest of her stuff from my apartment bc I was moving. We ended up having a conversation and she said that she had no relationship feelings for me and that she should had never had asked me if I was dating anyone. Then, when she got home, she sent me a message saying she was upset and cried the whole way home. When asked my was she upset, she just said I dont know. So i left it at that.

A week later, she went to a family wedding that I was supposed to go to, and I sent her a message saying that she looked gorgeous and to tell the bride and groom congrats for me. She said thank you I will. The next night, she got home and then went out "with friends". I asked her if she was out on a date because, 1 she always tags her friends when she is out, and 2 she never goes out on weeknights. Well, after I asked her and she said no, she ended up blocking me about 24 hours later on Instagram and only Instagram.

Im just wondering why she would block me all of the sudden? Is she doing it so she cant see my posts and is trying to move on and cant bc she knows she gets upset if she sees me out? Or did she block me bc she doesnt want me to see her posting anything and doesnt want me to get jealous? It has been a week and she hasnt unblocked me, and I know I should just give her space, but Im just very confused and I dont know what to do. I really want her back.

Any advice on this would be greatly appreciated! Thank you!
