Please help me find this one

I don't remember the details too well but it was a bl I think in the future or something along those lines. I'm pretty sure the MC was a blond? Anyways, I'm not sure if it was something with rebirth or him giving up, but after doing that and trying to divorce his husband he runs away.

I do remember that there was a scene where he was almost fully out of the car pointing towards the MC saying "I want this one!"

So he pretty much forced his crush to marry him and I think the crush was someone pretty high up in the military chain? I'm pretty sure other planets were involved but I no longer remember Σ( ￣□￣||). Please help!
