What does 🙈 mean?

So I texted this girl if she was coming to class today, and she just texted me โ€œmiss you ๐Ÿ™ˆ โ€ and nothing else. Iโ€™m back into the dating scene so Iโ€™m out of the loop. What does it mean when a girl sends you โ€œ๐Ÿ™ˆโ€ during a text? And also, did you think that was a positive text I got? I havenโ€™t texted her in a couple weeks if that matters.
