Addiction has clouded my connections

In my past relationships i never realized how closed off I was because i didn’t have to form super deep bonds with people, i always had my vices to “fulfill me”. But now that im starved of that fake connection that pmo gives, i want to connect with people, especially my current girlfriend and really get deep. The problem is, i don’t know how. I thought i was being true and vulnerable and fully knowing her, but we came to the realization the other day that we’re still kind of strangers. We know all of our favorite things and stories from our pasts, etc. but it feels surface level still. I don’t know where to go from here.
