I (49F) have been with my partner, let's call him "Doug" (42M), for two years, though we were best friends for a decade before that. ​In this relationship, I do everything for him. I cook, clean, handle the laundry, take care of his pets, and wait on him hand and foot. I am always available for him in every capacity. Despite this, he has never once told me he loves me. When he leaves for work, I am lucky to get a peck on the forehead; almost always, it is just a hug. He has never kissed me, except for once on New Year's Eve. ​Since we officially became a couple, I have repeatedly caught him engaging in inappropriate behavior. I have woken up to find him on live-streaming apps (like Tango, Ti Live, etc.) talking to other women. I took it upon myself to investigate further and discovered dating profiles he created while we were together, the photos on these profiles were taken inside our home. It was mine before we were together, he moved in with me a year into our relationship. ​Beyond that, I have woken up in the middle of the night to find him watching porn right next to me in bed. I know some people might not see this as a major issue, but to me, it feels incredibly disrespectful when I am lying right there next to him. ​I have pleaded with him multiple times, expressing how deeply these behaviors hurt me. He will stop for a short period, only to revert back to the same patterns. Every time I confront him, he refuses to end the relationship and turns it into an argument; he simply doesn't seem to understand that this relationship has left me depressed and completely over it. He refuses to leave. I don't want to which him and have that on him forever. ​I truly loved him, but I have reached my breaking point. I am ready for this to end. Because of the way he reacts when I try to discuss our problems, I am currently making secret plans to move out while he isn't home so I can end things without saying a word. ​Am I the asshole for leaving him this way?
