What does it mean if she send this emoji (😌) to another guy?

Recently my partner has been talking to a guy who I think she may be catching feeling for him and I’ve bought it up to her a few time and all she says is that’s “his just a friend” now I’ve been going through some of her text between the two and I’ve seen a lot of Flirting because she can’t seem to tell the truth…. I may be in the wrong here but finding out the truth is better then lying.
