Search Results: talking to a married man

So, he is our teacher, we have girls only in the class, here are some things he says -
"Everyone, you shouldn't hang out with boys."
"I don't think men and women should be friends. Only men-men, and women-women friendships are acceptable"
"If every boy treated every girl like his sister, that would be so nice, a boy cares for his sister a lot, but let me tell you, while your brother may care for you, but he must be harassing other girls."
"If I caught you talking with boy, I'll beat you up!"
"You people are in contact with boys even if I told you not to, right? He will certainly harass you in the future," he added in mocking voice, "Heeyy, I know your husband, if you won't have sex with me, I'll tell your husband that you have had sex with maaanyyy people!"
"All men are stupid, women are more intelligent."
"I don't let my daughter talk to boys too."
"If a boy has a bike, he must have had earned it through bad ways, for example, stealing!"

According to him, all men are satan, devil, dangerous, stupid EXCLUDING him! And all women are pretty, innocent, pure angels!

The irony is he's a man, yet he hates men this much and is spreading misandry.

He's married and is 48 years old.
We are 18-19 years old.

I'm in this situation
I've been with my boyfriend for 2 years
I really am in love with him
He's close to few people at his work and his gym
But he stopped talking to the guys at the gym due to reasons and he stopped talking to his other friends he met from high school as they all become distant from one another
And he doesn't hang out outside of work with his work friends
And he stopped talking to his family because he had really bad history with them from childhood because of physical abuse from his father and no protection from his mother
So anyway
At first I was fine with this
And I have introduced him to most of my friends and now we're all friends
But ever since his birthday, I was thinking about few things
I organized his surprise birthday party and invited my friends
Then all my friends are all questioning me like
"where's his friends?"
"doesn't he have his own friends?"
And then I had to kind of explain why

But it kind of hit me...
Especially when my best friend said to me "make sure he's not dependent on you, like people that doesn't have any friends or not close with family, needs someone there for them, they're very fragile people"
And then I told her "hes not really clingy though, he has 2 jobs, he's focusing on his swimming training and gym most of the times, and he doesn't mind seeing me once or twice a week but he does call me every night to talk, but he's not dependent on me"

But then Im thinking to myself "what if we get married? Who is he going to invite to the wedding? Is it just going to be only my family and friends? Who would be his best man? Etc etc"

Is it a bad thing if you date someone that is not close with their family and doesn't have much friends?
I really do love him
Im so in love with him
he's such an amazing guy
He treats me right
he's so caring and affectionate
he's always there for me when I needed him
he's never cheated on me
he's the best boyfriend I've ever had
