My 50m husband refuses to work (I'm 45f). He insists he's unable to due to being disabled however no doctors have ever suggested he's unable to work or recommend he start the process for filing for disability. He has a history of a mild TBI from a car wreck in his 20s and had seizures following a tick bite (he also had febrile seizures as a child). The seizures have been well controlled with medication for almost 25 years. He sees his neurologist one a year for a quick med check and has routine labs drawn by his primary care physician. He is in otherwise good health.I am the sole source of income and while we aren't hurting for money, we don't have any chances to save and rely on my parents for loans (which are always repaid in full) for any unexpected purchases and expenses. We are unable to afford vacations. He spends his days smoking marijuana (medical patient) and cigarettes all of which I pay for. He sleeps all day and stays up late playing games and watching YouTube. He does help out with household responsibilities (laundry, dishes, routine cleaning) but I had to threaten to kick him out before that started. We don't have children. He has quit so many jobs for no good reason and typically has grievances with other coworkers which are typically petty and immature. I'm at a crossroads because I can't keep living like this. He tells me he's looking for work but he's not. He's highly educated but I will admit his field is niche so this can create challenges for working in his field especially given where we live. I've tried encouraging him to do anything he thinks would be interesting, even part time work. I've told him that it doesn't matter if he works in his field or not. He says it's not fair for me to put so much pressure on him to get a job due to his health issues but from my perspective it's not that he can't work, it's that he doesn't want to. He is very emotionally reactive and hypersensitive. I've spent YEARS encouraging him to go to therapy and to talk to his doctors about how his medical stuff keeps him from working but he refuses. I think I deserve better than this but I also fear there is truly something wrong with him and I would be walking out on someone who is honestly trying their best. He tells friends he works remotely but I think they suspect he's not working based on how little we do. We're dinks and I aspired for life to be much different than it is now. We met in college and some of these behaviors were present then but I take into account that some of these behaviors were the norm for college life. Do I attempt to continue to support and encourage him? How does that even look as I have done so much already? Do I end the marriage over this?
Tldr my 50/m husband won't work and insists he's disabled. I don't think he is and can't keep this up. I'm at a crossroads.
