Am I in the wrong here?

I was in a friend group and everyone kept pushing for me and my now boyfriend to date. We finally started dating and now my friend is mad that I’m not hangout with her everyday anymore. We still hangout a lot though. She then got mad at me because I didn’t like a few of her Facebook comments she tagged me in and didn’t Snapchat her back all the time but I still did Snapchat her just not every single time back. I explained to her that we just started dating and want to get to know each other. And then when we would hangout she was not herself with me. She would talk rudely to me and it seemed like I couldn’t do anything right anymore. Then she started hanging out with someone we both didn’t like because she treated both of us but mostly me like pure shit (that’s a whole different story) and they turned against me in a way and they would send me screen shots of stuff I tagged my boyfriend in and call me ridiculous that I would tag him in such posts (they were memes) it came to a point where when I would try to talk to them they would make faces at each other so I cut them out. I deleted them off all social media because it was really getting to me and I didn’t want the negativity in my life anymore. I’m now very happy in my relationship and we have a baby together. They have been making me seem like the bad guy to my family. Am I in the wrong for cutting them out? Because some people think I am. Also for the comments asking how old we are we are indeed adults. That’s why all of this shocked me. I don’t act like that nor do most people I hang with
