It is quite problematic in that she seemingly lets her self out that easily. However, you do not have to worry if she has turned a new leaf and knows within herself that it is not a path she wants to go down anymore.
Furthermore, if she is honest with you (understandibly under the influence) but nonetheless, candid, then she cares enough about you to tell you the truth.
In my opinion it is a judgement call that I know is difficult and the interracial relationship thing should not be an issue at all!

Good luck bud-
