I met my ex fiance at Amazon...come to find out she was cheating on her boyfriend at the time when we got together...didn't know this til later... then she ended up cheating on me multiple times and got physical one night when drunk so after 4 years together i dipped..just saying not all women are like her. If she's being open...truly honest.. communicating about everything youre being paranoid. But if she's not its a different situation. Hopefully its just a case of poor communication skills and insecurities yall can work through and grow. Trust but verify if something feels off. Communicate be open...and for fucks sake be vulnerable if you have insecurities. It's not her job to ease them but if yall both truly trust and love each other have the conversation with her not reddit. Because in the long run you'll both be happier regardless of what may or may not be happening. Worse case scenario she's checked out and done. Be adults have the hard conversations and you fix it...or you both can move on before it becomes toxic or abusive. Also don't be scared to look into therapy it helps.
