The following sentences consist of my humble perspectives that are attempts at objective reasoning based on research on numerous interconnected, pertinent topics of which your story seemingly comprises.

After reading your post, he emotionally and psychologically abused, manipulated and used you. Moreover, you are a victim of such abuse, manipulation and use. Some quick examples of his tactics are shifting the blame to you, convincing you of invented guilt, isolating you from others, intermittent reinforcement, neglecting you/your wants/needs/life/interests, and more.

Your story also consists of numerous aspects that are strongly associated with relationships with someone, who is of Narcissistic Personality Disorder (NDP.) He may or may not be of NDP and/or other personality disorders. A few instances of such associations are his transiency, his conditioning of you to become addicted to him, his conditioning of you to become dependent on him/his attention and so on, hoovering and more.

Regardless of possible personality disorders, his behavior and actions in general were psychologically and emotionally abusive, manipulative and using. So, not only was this a toxic relationship, he was also abusive.
