I was never really close with my mother. We would eat dinner in separate rooms. We grew more and more distant throughout my teen years and when I was 20 I decided to disown her and we're now estranged.
There were multiple attempts to "get back" but none were successful. I think what I realised in the end was that she was too much of a free spirit. She wanted to have her separate life and have me co-exist in it, without dedicating herself to me like a parent normally would.
I don't think I'll miss them or feeling anything for them when they pass. My mother, maybe a little. My father, not at all. But I don't forsee being at her death bed, even if she told me she was dying. Maybe I'm just stubborn or am held captive by a matter of "principle and integrity". If a relationship is cut off, then it's cut off. Meaning you both have to deal with the good and the bad. I've decided there's more good than bad.
In some senses it feels like I never had parents at all. Like there's nothing to miss, because how can one miss an absence?
I hope though to be the parent I never had to my daughter. Unfortunately my partner has stage 4 cancer so won't be around for most of my daughter's life at a very young age, but that's okay. This is life and life is me.
