I went to my girlfriend's house, smoked a cigarette on the balcony after dinner, and her father drove me away. What should I do?

My girlfriend Xiaoli and I are college classmates. Xiaoli and I got married after dating for five years. Before pulling the card, Xiaoli took me home to meet my parents at her home. Xiaoli's mother is very gentle, but her father is a very serious person. However, I'm not afraid. I can see that Xiaoli's mother likes me very much and is very enthusiastic about me. In contrast, her father kept looking at me, and his eyes were very critical, which made me a little unhappy.

At dinner, his father also asked me a few questions about my work, which was hard to say; My parents divorced a long time ago because my family was poor. His innuendo was a little bad for me. This makes me very depressed. But for the sake of my beloved woman, I decided to put up with it.

After dinner, Xiaoli and her mother are packing in the kitchen. Xiaoli's father continued to question me. I can understand that he cares about his daughter's happiness, but many of his questions are really aggressive.

Under normal circumstances, I must have saved face, but I put up with it for Xiaoli's sake. I felt terrible when he finally stopped prying into my parents' unhappy marriage. Xiaoli's father went to the bathroom, and I went to the balcony to smoke a cigarette.

Unexpectedly, when I came back from smoking, Xiaoli's father came out of the bathroom and watched me put out the cigarette butts and throw them into the trash can. He rushed over and slapped me twice. I was confused at that time. I wonder why he is so excited. I told him to get out of his house as soon as he finished playing, saying that he had long since disliked me. Xiaoli and her mother also came out of the kitchen. So I was kicked out by her father.

When I got home at night, Xiaoli came to me and explained the cause and effect to me, but I froze in place. As a result, she said that her grandfather just smoked too much and died of lung disease early, leaving her grandmother to raise three children alone, so her father was very sensitive to smoking.

Xiaoli also said that her father was a little grumpy, but he was still a good man. He felt sorry after hitting me and hoped to get my forgiveness. Xiaoli has been trying to comfort me.

In order not to worry her, I have to say that I understand her father and I am not angry. But how can my beloved Xiaoli know how many ugly words her father said to me? I am ambivalent. On the one hand, I love Xiaoli deeply and want her to be my bride and give her a home. On the other hand, I don't know how to get along with her father in the future. What do you think I should do?
