<human>: Can you summarize the given text in a few sentences?

I've been in committed relationships since high school. I've never had the opportunity to fool around or explore other ladies and other perspectives. My high school sweet-heart lasted 2yrs then 3mos later I was with this girl. We've been together for 6.5yrs now.

She is beautiful but has gotten complacent, out of shape, and overweight. This has crushed her confidence. She has no interest in working out. She want's a magic pill or diet to fix her image problems. 

Originally, video games and art brought us together but I faded out of art and more recently, out of video games. I may play 2-8hrs a week rather than the 2-8hrs a day I used to (and she still does.)

I love her to death but I want to be "free" to do whatever, whenever, however. About 6 months ago I started working out, this has only amplified her insecurities. It's to the point she gets jealous\worried if I simply talk to any other female.

I know if I leave her, there will be a legion of men lined up for her. I may never see her again. She holds grudges like no other... I think too if I leave her, she may get motivated to make changes in her life, hopefully for the better. Most people do not make changes until they are made uncomfortable, she is no different.

I love her, I always will, and I want the best for her. As it stands we are roommates who fuck occasionally. The fire is gone, there is no passion, and I feel like we stick to the relationship for "convenience".

Then there's the family. I don't have a bio-family. [dead]. Her family took me in. They love me. They are my holidays and vacations. They support us, offer help in times of need, randomly show up with gifts and food, randomly invite us to dinners. They are great people, I love them too.

Are there any married couples out there that have been married for 10yrs+ ? How do you do it? Is the convenience\company worth tolerating the absolute boredom?
<bot>: In deep, scarce sex rations, love her, would kill for her, but might starve if I stay. Nothing jump starts sex drive, 6.5yrs together, great family, bored.
