If she was just trying to brush you off, she wouldn't have stayed in contact. She does care about you as person, apparently, beyond the romantic relationship that you had. Amazing.
But I agree with what somebody else said; stay away for awhile. Until you grow away from her a little, your heart will be easily confused; it is very likely to misinterpret any friendly interest on her part as romantic intent: 'She wants me after all!'
