Wife turns out bi, or whateer they call it.....?

i met a fake church going woman who acted and fooled me into believing all that.1 yr into the marriage i found out she has always been looking for other women in the area.now this is realy affecting me finding another woman because now i feel a woman with female friends is or has the or bisesual traits in her.i know this is not correct .i would like to hear from anyone with a tangible input about how to get over this.she has since been gone enjoying her life and i cant seem to get over that betrayal.
