Is my bf falling out of love?

I’ve known my bf 3 years before going out. We’ve been together for about 9 months now. He’s in the military so that makes things harder. But the point is, about 2 weeks ago I had a full on breakdown infront of him. I was bawling my eyes out and was telling him how stressed, depressed, and overwhelmed I was feeling about life.

Ever since then he’s just been so distant. I feel like I pushed away. Or I made him realize that he doesn’t wanna be with me anymore.

Since he’s in the military we can only communicate through text right now. I noticed he stopped calling me “babe” and using typical lovey dovey emoji like before. I asked him why he stopped and he said it just does feel right.

I know it seems childish but idk it just really feels different since that one night.

I know he’s been stressed out bc of his work. So should I give him some slack from being so distant and un loving. Or should I ask him if he doesn’t want to be with me anymore?
