Romance stories?

When I write stories, either shirt or long, I always have romance in them or at least most of the time. I start to wonder why I write romance stories. I wonder if I'm any good at it too. I've had six boy-friends and I've never really loved any of them. So I have no idea what love really is, yet here I am writing about it. Does that seem right? May be I write romance because I desire it, or I just like to hear and read about it. I like to make people happy, but I'm selfish cause I only think of others and never myself. I don't plan on getting married or having kids. I want to like in an apartment or hotel room and be alone.
Sitting there on my computer writing to the ends of the earth. I guess that's a little sad, but ...it doesn't really matter. At first I thought of suicide after high school, but that won't happen. I want to see if I can really survive in this crazy world. So I hope I can get some ideas on my problem with writing love stories when I know nothing of the word, or live without an answer. Either way, I'm not going to stop writing cause it's just too fun!
