I'm so sorry you were cut off like that and pushed away. That really hurts. I can almost feel the pain from here. Been there. :'(

Not much you can do really, at least not about the friendship. He's married and you're pretty much an ex. We don't know this but some spouses have problems with their SOs having contact with their exes. Could be that. Could be the military thing. It might be a variety of things that he's going through that you don't know of, and he might feel the need to keep things simple. Going into the military is a major life changing experience so it's likely that could be part of it.

All of that doesn't matter though, I only tell you that to comfort you.

Thing is you need to take care of you and your feelings. He is gone and you can't dwell on this. I can't say it will be easy and I won't lie and give you some magic solution that doesnt exist just to say I gve you advice. I will say that finding your way of coping is what you need to do, whatever it takes. It's not whether the pain will never go away, it's getting through the pain that exists right now that is hard.

I'm sorry I wish I had a soluton for you. Just know you have friends here if you need to vent or need support
*hugs*
