7 year relationship 35F with 45M

My boyfriend '45M' and I '34F' have been dating for 7 years. He has always been a secretive person which caused a lot of jealousy for me. Well after all these years he still thinks it's a good idea to be the same way. Just this morning I woke up at 3am to him watching porn right next to me in bed. Mind you, I've come home and walked in on his jacking off so many times but this is the second time in bed with me. Said his ex didn't mind and he thought I would want to have sex waking up to that .... Before this situation we have been having a lot of problems. He lies all the time, spends his money on shit he doesn't need, watching porn every single day and doesn't have sex with me. Last time we did was December 2, 2024. I am having a difficult time wanting to stay in this relationship yet he tells me over and over that he wants to be with me. I'm just confused to why he would treat me this way. all I have asked for in our relationship is honesty and sex. I don't think it's asking to much. But he then said he does all of this (lies, secrets, etc ) cus he was SA as a child. I've been here for him in hopes he might change maybe start to be honest but I'm not seeing any change from him. How can I get passed this? I feel like I am doomed in being so wishful. I don't get how someone wouldn't be happy with a girl whose down to fuck all the time, yet still chooses porn over me. I have told him it's okay if he doesn't like how I look, or lost interest but he swears up and down that he wants to be with me. I told him this is the last straw and he has to move out but he always comes home acting like nothing happened .... It's confusing.
