Yeah of course most girls are going to be looking for long term relationships. As a general rule that's how women work.
You are not going to find many women who will openly admit they are looking for quick no strings fun as it makes them seems like sluts.
But, girls don't only sleep with the guy they think they are about to marry. It just means you play it a little longer and put a bit more effort in.
You can always bail in the early stages of a relationship, you have no obligation. She might do the same...
