You would want to go to
my website (or tell your friend to do so) in that we have several articles dealing with this issue...
IDK what to tell you to tell your friend? It sounds like she allowing "external things" define her "internal truisms". And that is what needs to be sorted out before you include a someone as a mate in a longterm relationship, IMHO.
Also, There is many GC AKA Ave women on here that are over 35 years old. I think a handful of us are married. So there are numerous women that are unmarried, or without a relationship, and lonely. But, I can tell you in my committed 5 years, I get extremely lonely at times even when my husband is next to me snoring... There is no such thing as girl-talk with a husband. LOL.
