Newly moved in together

My man and I have been together for about 6 months and it's honestly the most comfortable I've been in a relationship, especially having dated a lot of losers users and abusers in the past. He's grown, (he's 26 and I'm 22) good job, education, car, smart, not much temper, tons of common interests. We click great we've never had a real honest to God fight which is such a refreshing change of pace from all the turmoil in relationships past.

So we signed a lease together last month and got a place. He was living with his parents paying off school loans and I was living with a douchey roommate so it was a good move for both of us in terms of adulthood and stability.

And honestly it's been great so far. But I keep getting this feeling like it's too good to last, wondering when and how we'll fall apart. He says he doesn't think about how or when we'll end, but from my past I can't help it. The last and only time I lived with a guy he turned out to be a completely abusive asshole.

Anyone else in similar situations with past boyfriend trauma and/or breakup dread and/or living with someone but feel the pressure to make it work?
