well, it sounds like you are seeing the relationship as not being fair to him if I am reading this correctly and that you feel that what you have to offer does not equal what he gives to the relationship and you feel you are draining him and that isn't fair to him. but in divorcing him, you think that would look like you have used him. I don't see it that way. you are unhappy. you lack common ground. things are frustrating. he doesn't give to you in the way that you need to be understood and supported. the only reason to stay is financially. but that would be using him. I could see discussing yur needs first, seeing if you could find common ground. but if not, being alone is not such a bad thing. I rather enjoy my freedom.
