Am I just another option to her?

I’ve been kinda seeing/kissing this shyish girl for about a month now. We first kissed back in March and a couple of awkward months followed where neither of us understood how each other felt. Presently, I feel like I’m stuck in a bit of a situation. We’ve kissed on several worked nights out and have chatted lots about our situation, but I’m still confused. I asked her out about a month a bit ago out of the blue and she declined stating that she was only out of a thing (which she was), but I seen her on tinder and that pissed me off.
Two weeks later we were out with a mutual friend, she went home and we kissed and talked and she said she felt bad for “rejecting” me but claimed that I believed she was easy, which obviously isn't true.
It happended twice more but last week was different. She called me late last week Friday and asked if we could meet up in town which we did. She said that we have a connection but was still so stubborn in relation to saying what she wants. Is she being sincere or am I an easy target to give her attention?

I feel like she wants me to make a move now in terms of asking her out, but after being “rejected” the last time and her claiming that she only wants casual has totally put me off.

Am I just another option to her?
