Marriage and Mate Chases (слэш)

A Regency-ish AU:
Strict, stern Alpha Captain Steve Rogers is firmly in control of himself, his army, and his life and intends to marry an Omega who shares the same ideals while wild, flighty Omega!Tony loves to flaunt Howard's rules, society's expectations and has no intention of settling down.
An arranged marriage forces Alpha and Omega together, but Steve's constant disapproval and Tony's refusal to compromise leads to anger and arguments, missed heats, harsh ruts and a lack of bonding bites. Vicious rumours fly about the Omega's fidelity and the Alpha's ability to control his mate and when Steve runs away to war to distance himself from his unpredictable husband, Tony turns to new friends and illicit activities to hide his hurting heart.
Steve returns from war a changed man ready to be a good husband, dedicating every minute of every day to winning Tony's heart back, but Tony is tired of being ignored, busy with his own projects and unwilling to give the Alpha another chance.
With outside forces plotting to ruin what little happiness they have, are Steve and Tony doomed to be unbonded husbands, married but never truly mates?
