Blake Moynes suspects an emotional affair between his ex Katie Thurston and John Hersey.

Hersey was a contestant for 2 weeks on "The Bachelorette" but lost Thurston to Moynes.

Moynes feels speechless that his ex-fiance moved on just two weeks after their breakup.

The wildlife conservationist accused Thurston of emotionally bonding with Hersey while they were engaged.

Moynes thought nothing of Thurston and Hersey's friendship because he is a secure and confident person.

The nature lover feels "stupid and foolish" and believes he probably emotionally deprived his ex.

Nevertheless, Moynes wishes the couple his best and looks forward to his "next chapter."

Thurston announced her breakup with Moynes two months after their engagement in "The Bachelorette" season 17.

The 30-year-old said the split was their "most caring decision" born from mutual love and respect
