Hey could someone give me a perspective what would you do in my situation? Eating me alive lol..

So basically i met a girl in a bar, we hit it off but nothing happened. So few days went by and she basically said that she can't seem to get me out of her mind. After little chatting she said that she is in a relationship but her man works abroad so she does not see him that often.. So fast forward few days i basically pushed her really hard to meet me and she did at her place, we made out and did basically everything but sex. Next day she said that it can not happen again and she feels guilty. She also said that if she wasn't in a relationship things would be different.

What do you think? Will she contact me again? Should i just let it be?

What is the most wise thing i could do? My own mind is practically blind how should i proceed.
