I've very recently noticed this with my 'best friend'.
We've been very close for almost 20 years, and planned to move to the coast when we retired.
Last year, we found two properties practically next door to each other, her offer was accepted, mine wasn't, but I wasn't too worried because there's no rush for me to move just yet.
I've helped her with hospital appointments, been to her home when she was planning to go climbing a ladder to get stuff out of the loft, just to make sure she didn't injure herself. Every time I went over, I took a meal with me for us to have and there was always enough for 3 or 4 servings and I left the remainder with her for the next day.
She's never been to my home, and I've never asked for her help with anything, so now I'm feeling it's been a very one-sided friendship.
There have been so many delays with her house move that it was almost 14 months between putting in the offer and actually moving.
So understandably, she's been a bit anxious about her old house for a few months, especially with all the interest rate increases, so I'd been as supportive as I possibly could be whilst we waited for her moving date. I knew that as soon as she moved, all those issues would no longer be a problem as she was downsizing and would no longer need a mortgage.
She finally moved 6 weeks ago and simply sent a message saying "I've moved".
I sent her a lovely message saying how pleased I was for her and that hopefully she'd be a lot happier without all the problems of the old house.
I didn't get a reply.
I waited until she'd been there for a month and sent another message, saying I hoped she's settling in well and is happy. That was a fortnight ago and yet again, I've had no response.
I'll give her another couple of weeks and I'll message her again to see whether she actually wants to remain friends, but I'm not holding my breath for a positive response.
Maybe I should have worked out a long time ago that I was being used, but knowing this now, I'll be a lot more careful not to let myself be walked all over again.
