When he went barhopping with Lydia, the ML knew exactly how it would end, and that is, he would sleep with Lydia . Maybe he was a little apprehensive of the inevitable that he overdrank himslef and ended not performing. He knew he was really getting drunk, so, if he didn't have the intention of sleeping with Lydia, he could have taken a cab home. In fact, he did think he had really slept with her, and hence he felt really guilty. He tried to rationalize it by blaming it on his wife.... that she wouldn't let him touch her. I really believe he was dating Lydia, but had not reached the point of having sex with her , YET. Again, his excuse was that Lydia was there when he needed help, day in and day out. Everyone knew he was dating Lydia. Everyone could see the fire starting between the two. Even Zac had heard of the "rumour. " If there's smoke, there's fire. That's why, he didn't want to be seen by his friends when he finally went out for dinner with the FL, his wife. Everything else was either implied or left unsaid by the author in this manga. I bet the novel is more direct.. The Title says it all. The Ultimate Betrayal.
By the way.... the fact that he would always smell of woman's perfume when got home is practically an indication an affair was on-going.
