military partner deployed 6 months, weve agreed i can play solo... is this gonna wreck us

hes army, just shipped out for a six month tour. before he left we had THE conversation about what happens while hes gone. we already do LS together when hes home, weve been at it for two yrs and its been great. he was the one who suggested i could see ppl solo while hes away, said hed rather i be honest about it than have me lying or going without. im keen but also terrified. how do u handle this when ur partner is literally unreachable for days at a time and cant just talk it through if something feels weird... anyone else been thru military deployments in the LS
