Strict bedtimes, extreme jealousy and black eyes are just a glimpse of what the wife of a German diplomat said she had to endure at the hands of her tyrannical hubby — who cannot be arrested by the NYPD because of immunity laws.

Most recently, Joachim Haubrichs, 56, punched his wife Henna Johnson, 35, in the face at the couple’s Upper East Side home after he went into a rage because it was 7:30 p.m. and Johnson was still on her phone, which he strictly forbids, police sources said.

“He’s very controlling. At 7:30 p.m. the cell phone should be off. I’m not supposed to talk to anyone. Then 8:30 p.m. is bedtime. Whether I like it or not, I have to be in bed,” Johnson told The Post Wednesday at the couple’s home on East 88th Street near First Avenue.

Johnson was texting with a friend Monday evening when her husband of 16 years flew off the handle.

“He said, ‘It’s already 7:30.’ I said, ‘Give me a little time. Give me a minute or two, I’ll finish up,’” Johnson recalled. “But because he’s so jealous, he starts screaming. I sat on the couch, he started throwing pillows. That made things worse.”

When the couple went into the bedroom, Haubrichs socked his wife, leaving her with a nasty shiner on her left eye and some bruising to the back of her head. The force of the blow knocked her against the wall.

“He hit me against the wall and I hit my head,” Johnson said of her husband, whose title is assistant attaché to Germany’s Permanent Mission to the United Nations.

Haubrichs claimed that he remembered nothing the next morning and was extremely apologetic, said Johnson.

On Tuesday, Johnson reported the incident at the Family Justice Center in Lower Manhattan, who in turn contacted the NYPD.

After being made aware of the incident, NYPD brass told cops not to arrest Haubrichs. Tuesday night, officers visited Johnson at the home and told them it was not a good time since her husband was home.

Johnson, who refused medical attention following the incident, has been in contact with the NYPD by phone and Mayor de Blasio’s office.

“What they are suggesting is, it would be best for me that I should pack my bags and go to a hotel room because it won’t be safe for me otherwise, and they are going to contact my husband sometime today,” she said.

An NYPD spokesperson said that there is no situation in which it is acceptable for an officer to apprehend someone with diplomatic immunity.

The mayor’s office has urged her to go to a shelter for domestic violence victims, said Johnson, who is resistant of the idea.

“Other than a shelter, I don’t have any other options and I’m not willing to go to a shelter,” she said. “I don’t think I’m made for that stuff. All my life, my husband has been providing for me. He has been keeping me secure. So I don’t really know the world outside.”

Johnson, a native of Pakistan who does not work, met Haubrichs in her homeland when he was working in the German embassy there.

The childless couple has moved all over the world wherever Haubrichs was posted, and lived in America for a little over a year.

Monday was not the first time that Haubrichs has become violent with his wife. A similar incident between the pair in February left Johnson with a black eye, she said.

Throughout their marriage, the pair has never been out to dinner and Haubrichs has even gotten “jealous” over a cat the two once had.

“He was jealous of the cat whenever the cat got close to me. He said, ‘I love you too much to share a room with anyone,’” Johnson said.

But she still loves her man and doesn’t want any consequences to rain down on him.

“I’m concerned for him. I don’t want him to lose his job or his title,” Johnson said. “I do want to have a respected life — of course, nothing like this — but I love him very much, I don’t want to compromise his career or position.”

Johnson, who wants children, but her husband doesn’t, described Haubrichs as “a very nice person.”

“He’s a very caring person. It’s just sometimes the anger gets out of hand and things happen,” she said.

Germany’s Permanent Mission was not available for comment Wednesday.
