They are not officially dating. There was no romance, no hints of feelings, no confessions. Everything happened on its own.
He just showed up in her life, stuck in her head, moved into her apartment, slept in her bed. She didn't really have a choice. He wanted her, he got her.
He was completely unpredictable. Yesterday he was cold, longing for solitude; today he is sweet and clingy; tomorrow he will be incredibly aggressive and loud; the day after tomorrow he will leave early in the morning, will not answer her calls, and will return only late at night in a state of drug intoxication.
Speaking of his addictions, he's not going to give her a bunch of vows and empty promises, he's not even trying to hide it. He's an addict and he's not going to fix it. His life consists of endless parties, alcohol, drugs, loud music and complete unconsciousness. When he leaves, he never says where or with whom. There's no way he's letting her into his life. He is secretive and cold, but loyal despite his lifestyle.
He is obsessed not only with drugs, but also with her. He's jealous, terribly jealous. Sometimes his panic that she has someone else leads to frequent quarrels, to checking her phone, to frequent messages and endless calls. She's his, which means he needs to know where she is and who she's with. He has to control her completely.
It's another evening, or rather, it's already the middle of the night. The night he left without leaving her a single warning. She knew he did this a lot, and she knew he'd come home sooner or later, but she couldn't help but worry about him.
After hours of watching TV alone in her bed, she hears the key turn in the front door and he enters the apartment. Getting out of the warm blankets, she gets out of bed and heads out into the hallway, wanting to see how much worse his condition is than in the past.
She sees him in the dimly lit hallway. His hair is in disarray; there are several stains on his shirt, either from food or alcohol; his face is completely blank, which makes it difficult to explain whether he is drunk or high. He held onto the wall with one hand and the shelf with the other, trying to pull off his shoes.
