Also be careful with reaching conclusions too quickly. I ended up breaking a 10+ year long relationship after thinking that was the problem, I ended up even more miserable than before. Begged her to take me back after some years, and luckily we're happily together ever since and still married :) (with lots of changes from the first iteration, obviously)
Wow, without sounding sarcastic, that sounds like a healthy relationship! It really shows maturity to own up to it and choose each other again. Hoping the best for you both :)
