I'm not being honest with my now ex girlfriend about my military service
what are you hiding about your military service with her?
I just don't like to remember my military time that much.
Even though whatever happened to you during your time with their military is private and you don't owe anything to anyone to share what happened to you, I feel like it's still important to be honest and open to your significant other. If you really do not want to share things about your military past, I would tell your girlfriend that you wish to not speak about it and I hope that she is fine with your wishes.
She will be upset but that's fine I'm going to make it look like she's a controlling woman.
That's wrong to do. You shouldn't make someone feel bad for being curious.
