Things spouses can do on their own

Hi.  I'd like some suggestions for activities a spouse can do on her or his own when in a relationship with an ADHD spouse, particularly if the non is contemplating a formal separation or divorce.  I'm looking for suggestions both for activities that I should know how to do so as to live independently (e.g., home repairs) and activities that I can do for fun as a quasi-single person (i.e., a person who the rest of the world thinks is married but whose spouse is emotionally or physically absent or distant and thus not available for activities).  I'm reasonably competent with things such as cooking, cleaning, and taking care of finances.  I've been reading, watching movies, and listening to music more than I used to.  I'd kind of like to travel but have a dog to take care of.  Any suggestions?  Thank you.
