Omega's Last Chance. Poppy Field Mpreg Series, #8

Omega Rudy Charles uses booze to numb the pain of his past. He knows if he keeps going the way he has been; he'll end up dead in a ditch somewhere. He wants to quit drinking, but doesn't seem able to do it on his own. Feeling desperate, he reaches out to an old flame, who by all rights shouldn't want to talk to him. Alpha Harry Pearlson fell for Rudy when they met a year ago. They spent two great weeks together, and he thought they had something special.
But when Rudy ghosted him, and went off with some other alpha, Harry was hurt, but mature enough to simply move on. When Rudy calls Harry late one night in desperate straits, Harry just happens to be in Poppy Field. He shows up on Rudy's porch, unable to ignore the despair in his ex-lover's voice. Harry takes Rudy under his wing and helps him get sober. Rudy opens up to Harry, sharing his painful secrets.
Things go so well; it looks like this time around the two men will be able to make love work. But then fate takes a shocking turn, and Harry has to decide if being with Rudy is worth it after all.
