In a simple answer ... "yes"
I remember being in my mid twenties and I started really, really realizing that I was on a completely different wavelength as my at-the-time buddies were. My friends were all meeting what would soon become their husbands/long term companions. I still was not able to meet anyone even for a date
I started noticing that these "friends" would only call when they needed something from me (to borrow an item of clothing or accessory or to use something that I had - be it a connection or an item). They never seemed to want to call just to chat. They wanted to spend time with other couples and I was just sort of a peripheral acquaintance.
It was a painful time. I felt really alone. I tried to maintain contact with some of these friends, but one of them started getting plain catty with me.
We all drifted apart.
Since this time, I had an acquaintance tell me a wonderful thing (she had been married and divorced and was currently living with a new partner - she was wonderful NT and I am so blessed to have made her acquaintance). Anyway, she said, "people are in our lives for a reason and a season" When she said "season" she didn't necessarily mean "short term" she simply meant that most people in our lives come and go. My friends and I were suitable for each other in high school, but as we grew in different ways - it was time to move on.
My mistake, at the time, was not realizing that I needed to grow and "move on" in my own way. I thought that what my then friends were doing was the "correct" thing to do at my age. Looking back, the best thing I could have done was to disengage more from this set of friends and pursue my own interests (and perhaps another set of people) who were more suitable to me. When one of these drifting friends called for a favour - I should have said "no" politely, but firmly, and moved on myself.
Back to you goybandrocks, maybe you and the friendship with this person is ending its "reason and season." If the friendship makes you feel bad (you don't feel you can trust them and you feel used) - it might be time to start disengaging. Think of the things that you like to do. Join a meet up of others who share this interest. If you are verbal and high functioning - join Toastmasters or join a club through a church or social activity group. Meet other people and enjoy what you like to do. If you can't find anyone to do activities with - pursue interests on your own - it will keep you interested in life and interesting to others. Don't dis this friend and burn any bridges. Maybe in a decade or two - you might bump into each other and it would be nice to be able to either re-connect or at least share a pleasant conversation.
Anyways, this is just my opinion, based on what I've experienced/felt in the past and what I have learned through the years.
Good luck to you.
