How faithful are Gemini men

Libra queen here , been dating my Gemini man for 2 years. He's great. But sometimes I can't help but think he's playing me behind my back. Caught him texting his ex a few days ago. He begged and plead for my forgiveness. Don't know to believe it's sincere or not.

Tough one..because the Gem male already comes burdened with a reputation whether deserved or not that other Gemini have fostered.

Id keep a very close eye on him, but dont make noise and nag. Let him see that youre not stupid, and weak. Dont ever be a weak doormat in the presence of a Gemini. If he talking to her, thats not good though.
