Either she really wants him to become a solider, or he's not the guy you thought he was. And what on earth happened to you for you to only trust one guy? We're not all like Harvey Weinstein.

With time you’ll fall in love and trust another man. He’s not the only good guy on the planet :)

At least he’s still in Texas! Yeah I know that doesn’t mean much, Texas is huuuuge. There are other good guys out there OP. I know it sucks now, but you’ll be ok.

If he is being sent away for 6 years to a military school, that means he is 11 or 12. This also means you are most likely 11 or 12. You are also calling him your boyfriend. His mom probably realizes he's way too young for a girlfriend, as your parents should too.

if his mom can just send him somewhere for 6 years he has to be 12 years old or younger. in which case i hope you are the same age. that or he is an adult who lets his mother decide his life and that's not the guy you want. either way you need to get a therapist and work on those trust issues, it's not worth living your life alone over.

what did he do to get sent to military school?

You get that the internet makes it possible to keep in touch right? Plus there are letters and whatnot? Give him your address or Kik or Skype or snapchat and you won't lose him....

Military school for 6 years? WTF, are you 12?
