Just that really... I'm 38, don't live in my hometown anymore (haven't since I was 20), my DM is still there, DB also moved away. I just feel as I'm getting older and have started my own family, I'm just very different from my DM. Not necessarily in a bad way, we're just very different. I'm quite social and like having a houseful of friends/family whereas my DM is quite quiet and not keen on much interaction with others. We're just very different people in a lot of ways.
COVID hasn't helped.. obviously less visits has kind of really shown our differences and it's made her introvert more than ever. We live far away, so overnight stays are a must really, but despite having two vaccinations she won't stay overnight or come indoors/have us indoors.
We're due to move even further away at the end of this year due to work commitments, however we'll then be staying there forever, and I just feel like we're literally moving further and further apart in many ways.
