Quarreled with a girl

Good day. I live on the outskirts of the city, in a one-room rented kennel, I am 23 and I am bearded, not a virgin. There is a normal job that I don't give a damn about. There is money - and okay. In the evening - tanks, beer ... And she, waiting for me in our common bed.
She is special, very special. And also the most beautiful. What attracts me the most is her natural scent. Skin, body, hair. I like to stroke, touch, savor the feeling of velvety softness of her fur with her fingertips. I like to call her my sunshine, although she only responds to "princess" and "Miss Rarity."
Previously, the relationship was just fabulous, but recently we constantly quarrel, she believes that I always ignore her in the presence of other people, and I just do not want to advertise our relationship for now. What do you advise, how to explain it to her?
