hi davaidavai -- I'm a woman and had much the same experience as you. I followed all the suggestions -- sponsor, step work, I had a service position (secretary'd a meeting for 6 months), invited people for coffee, joined when others invited, said hello to newcomers & gave my phone number. After 16 months I really had not developed friendships -- there were a couple of women I could text or call, but they did not become friends to hang out with.
The hope of friendships had kept me participating, even after I felt the "dogma" was no longer helping my recovery move forward. I know that AA doesn't promise friendships per se, so I let go of that expectation. I'm an occasional visitor, and still practice the principles as I understand them, but I'm not involved in the way I was before.
AA is a lifeline ... but in my experience it doesn't answer my needs in every area, it takes effort outside the fellowship for that.
