I need some "me" time. I used to go out with my friends fairly regularly. Used to go and do things alone all the time. Lately, I have had to cancel my plans because H comes up with something he has to do at the last minute. Another one of my issues with "no notice". I have lost my mojo.
What kind of stuff does he come up with? I understand work or family illness or whatever comes up unexpectedly, but I think you are entitled to a night or afternoon off every week. If you give him notice, then he needs to honor that. Esp. since he isn't supporting you at this time, you need to take care of yourself, get support from others, etc.
