In the end loneliness is a choice. Everyone experiences bouts of feeling lonely, but to be clear we’re talking about perpetual loneliness here. And that is a choice.
You can choose not to hang your needs for human connection on a romantic relationship. A lot of people can choose not to hang their need for connection on a human at all. Dogs are great companions.
You can have a family sans a man, you can be an auntie. You can adopt a neighborhood or a charity organization. You can build a club based on a hobby you enjoy, etc.
At some point in time you have to realize that people can’t give you what they don’t have. If your guy is incapable of seeing you as a person rather than something to fuck, keep house, and give him money then he’s not someone who is capable of being a friend, or even being companionable long term or without condition. You either dump him and move on, find meaningful relationships to satisfy that craving elsewhere (I’m not advocating cheating here, non romantic remember?), find companionship in your own company, or you learn to deal with being lonely.
You cannot make someone be something they’re not. If he can’t or won’t be what you need because he doesn’t value that with you, you’ve got the same options everyone else has. Put up or shut up. Think it through carefully and make your choice but don’t sit on the fence whining and complaining your whole life.
