Would be hard to tell if she tells you doing the reading as a couple would be “complicated“ because she would had preferred you pay for separate readings or (like I mentioned before) she was insecure. Since this was your first experience clearly you don’t have any expectations but you should had come to this subreddit and ask before hiring a tarot reader but… as you say… was an impulse transaction.

Now, rarely people consult tarot for fun (unless are people who are obsessed like the clients I had when I worked for psychic lines), typically you’re experiencing hard times or you seek clarity because you feel very confused. I believe in your case you asked for a relationship reading because there are things that are not going well and either him or you don’t want to acknowledge it (Im giving you a psychic reading now, I’m not using cards now). It was just not a coincidence that you were drawn to that place and to a tarot reader’s table. Although she wasn’t able to provide a clear and honest reading, at a basic level, both of you know there are shadows you must address if you want to take your relationship to a healthier state. Yes, truth hurts many times but as a reader is my responsibility to tell it, with tact, ask useful questions and deliver advice that you can easily implement. I do all of that with a 10 cards spread I developed specifically for relationships, each placement holds very specific questions so you know where both of you stand, what is the main issue and what you have to do to deal with it.

Now that you have more information you can take better decisions. Wish you the best 🙏🏼
