You have some capacity for affection because you take care of your cats. Many real women will see that as a sign you’re basically a decent person, even if you don’t have practice with real human romance. That’s not necessarily a bad thing, if you haven’t learned a lot of bad habits. I guess one thing to examine is how positive or toxic the fictional romance is. A lot of things guys romantically do in fiction can be really creepy in real life. Even though you’re sane enough to manage in other areas, a therapist could be a good sounding board for evaluating this and figuring out first steps if you decide to try looking for human love. Maybe better than a bunch of people who are sitting around on a weekend arguing with strangers on the Internet instead of doing something with the one they love.
