Overthinking about him talking to other girls

At the beginning of this month I ended up hooking up with one of my good friends. The next day he left back to the military and we were talking nonstop since. Earlier this week he told me he thinks we should just stay friends because he wants to focus on school, work, and his religion. We’ve been discussing this the past few days and I’m still in disbelief. I was the hesitant one because it would’ve been a LDR and he was the one who wanted to go for it but he changed it so quickly. He’s been telling me he needs to be in the right place in all aspects of his life, especially his relationship with god before he goes into a committed relationship. We decided to remain really good friends. We’ll still snap every day but not as often obv, but sometimes he’ll read mine but won’t reply. And than I notice his snap score going up so I know he’s snapping others. Maybe I just never noticed how much his snap score actually went up because he used to talk to me all the time. I so badly want to straight up ask him if he’s talking to other girls but that’s prob not the way to go. I know he’s not the type of guy to lie but I’m just overthinking it I think. How do I get over this?
