Welcome to our SR family!
Congrats to your friend & his HP on his 9 months sobriety ~
How wise of you to seek out information on this disease as you enter this relationship ~ I would also suggest maybe attending some NarAnon or Al-Anon meetings, reading some of the literature so that you remain in a focused and healthy state of mind
Even in a "normal" (if there is such a thing - lol) relationship we can ALL tend to lose ourselves ~ I believe the tools of a recovery program can help us stay on our side of the street, keep healthy boundaries, not get caught up in what is in our "minds" and stay focus on what is real!
Best wishes for you & your new friend!
PINK HUGS,
