Relationship changing?

Hey everyone I’ve got a question that has me stumped. So I’ve been talking to this girl for awhile long enough to have strong feeling towards each or at least I do. But it seems to slowly get slower and slower with calls and texts and meeting and such but when she does call or text or meet up we do tell each other that we love one another. But it seems one day she we are all in and then the next I barely hear from her what could be going on i haven’t had this happen before and was just curious what it could be?
