About a couple days ago my friend stopped responding to my messages. I haven't done anything to hurt them and i've been trying to be a good friend but for some reason i feel like i'm being ignored. They're talking to their other friends and stuff and i haven't been blocked on their social media at all so can someone help me out here?

Just talk to them and ask. There will be no solution if someone will not do an action.Don't waste your time to wait for them, when you talk to them just be honest and let yourself to tell anything you want to say to them. Sorry if I have a wrong grammar (I'm not pretty good in english ^_^). By the way I hope it will helps you.

The reason why your friend is ignoring you might be because of other matters. Although, there's also the possibility of you not realizing you have done something wrong to them, like saying or doing something that they consider offensive. This is just a theory, but you should probably ask them about it and reflect on it if ever it turns out to be correct. Remind them that you can't reflect on you words or actions if you don't know what you have done wrong. The fastest way to mending your relationship is to talk with each other. However, if they continue to ignore you, there's actually nothing much you can do except to wait for them to be willing to converse with you, so it's best to just not think about it too much.

Ask your other friends to find out why she has a problem with you. They can ask her. This happened to me a long time ago. Still have no idea why my ex friend did this to me. No one else knew why either. I just decided to ignore her. Year's later, everyone thought she was a total bitch. She was known for being one. It was so confusing but after hearing about that, I stopped wondering.
