That's hard T. I think sometimes about when my dad dies and how that's going to go (morbid I know). Regrets are the hardest. You know you can't do anything about it, but that doesn't change how you feel in the moment. If you just want to vent, you know where my inbox is. I won't give you a bunch of platitudes, probably not a lot of answers either, but at least a place to just say what you're thinking.
You're not the only one. I think a lot about how I would feel when my mom goes. She's nearing 70 at this point, so there will come a time when she'll be gone. My feelings about her are mixed. Always have been. On the one hand, I don't hate her deep down, despite feeling that way at times after everything she's done to me. And I don't wish any harm to come to her (unlike my grandmother, who I keep hoping has fallen and broken her neck every time I hear a loud crash upstairs--but she always ends up being okay; I'm not that lucky). But as far as my mother, I have a lot of resentment toward her, but I do still care. I don't think I'd feel even remotely close to how I feel about my dad dying, but I'd still be upset. Mostly over the fact that she never really believed in me or loved me like a mother should. I spent so much of my life hoping that that would change someday, but it never has, and I realized it never will. I'm her daughter. Thus, she merely feels an obligation to care about me...and because of that fact, doesn't show it very well. So my sadness would mainly come from wishing that that was different.
My father loved this woman. He never got remarried or anything. He decided he'd rather be alone than marry some bimbo just to avoid having to feel that pain. Whereas she got remarried a couple of times after him because she puts on this facade that she's not afraid of being and dying alone. But she is. She's terrified of it. I guess that's where my own fear of being alone comes from, possibly. I should take the example of my father instead. At least he stayed true to the one he loved this whole time, despite the loneliness, and perhaps fear, that came with it. It's okay to be alone if you truly believe that there's only one person out there for you, and they're either no longer around or have moved on. In my mother's case, it was the latter because she's a narcissist, who acts like she's so strong and independent and stable. But in reality, she's just weak and afraid. Her mother made her that way, and she made me that way. So maybe the best way I can honor my father is to stay true to what I believe, even if the cost of doing so is being alone. Only problem is, I don't know what it is that I believe, as far as being strong and standing for something goes. I still haven't figured that part out yet.
