Resignation of a seo expert

A friend of mine moved to the United Kingdom a couple of years ago. He was offered a position as a polish seo at a popular British seo company. He hesitated a bit because he had to part with his girlfriend but in the end, he decided to go. The job turned out to be quite demanding, but he felt that was something for him. He was delegated a lot of tasks and could broaden his knowledge and experience in the field every day. His English also improved a lot. After six months, he decided to invite his girlfriend to the United Kingdom. She arrived in the city on Friday evening. He had taken a week off from work to spend some time with her, show her around the city and talk to her about their future. On Sunday evening they had an argument. She begged him to go back home and he wanted her to move to his place. Of course, this could not go on like this. On Monday morning, my friend did not know himself if moving to the UK had been a good idea or not. A couple of days later, he decided to hand in his resignation to the boss. He really liked his job as a polish seo, but he could not stand constant rows with his girlfriend. They came back to their hometown together two weeks later. Unfortunately, their relationship ended three months later.
