Am I doing the right thing?

I met this girl online and we ended up staying at the same class, she is in a ldr, I was sincere and told her that I'm starting to have feelings for her so it's better to talk less or only uni related stuff, but she acted very weird since then, one day she told that "I thought my feelings would never change but something seems wrong" and said that needs time. And since then she takes time to reply now too, so I think it's better to not start a conversation with her now, if she wanna talk with me I will wait her to message me first, I don't want her to have pressure and I don't want to act weird, she is working very hard for uni too so I don't want her to stress more. Am I doing the right thing? Thanks in advance.
