My (19F) boyfriend (20M) is jealous of the people I’m embalming at my work.

Hi, this is a long back story but I (19F) and my boyfriend (20M) have been seeing each other for 10 mos (official for 8) and he is genuinely one of the only men I have ever dated that has made me feel cared for and safe. That being said we have ran into a lot of issues in our relationship especially surrounding the topic of jealousy. My boyfriend, let’s call him Kenny, has been through a lot in his past such as being abandoned by his parents, groomed, and cheated on, which has left him with severe attachment issues; he is constantly jealous and worried that I am cheating or lying to him. There are many cases where he has acted jealous at the sight/thought of me having a genuine interaction with another man. Now, I don’t want to go too far into detail, but I have talked about this with him in the past and I can see that he is improving. We are also trying to find a therapist for him because he admitted that he did have an issue.

Now, the situation that came about today is related to how me and Kenny were discussing my career future. I am currently in the process of becoming a mortician, which has been my dream for a while and he has been aware of that. While talking about this topic, he made a comment about how me seeing another man with a larger dick would make him sad, now this disgusted me for many reasons. Not only is he sexualizing my job, but he’s also showing insecurity and jealousy again over a dead body. When I confronted him saying that it’s weird for him to say that, he continued to back up what he was saying and even implied that I would be jealous if he saw a dead naked woman who had a fatter ass than me. Now this genuinely left me in shock, I felt truly disgusted by him in that moment and literally can’t process why he would say something like that. I tried to communicate with him and basically said that it’s weird of him to even think of that or imply that at all because it’s genuinely perverted. He then told me it was just a sick joke, and he only said that to get a reaction out of me. I really don’t know what to do at this moment because I truly do love him, like I said he’s the only man who I have dated that’s treated me decently and also excels in all other areas of our relationship. I really want it to work out with him but I’m just so disgusted I don’t have any clue what to do. Any advice?
