I had a similar kind of relationship with my biological father. He was an alcoholic who was not overtly abusive but barely able to maintain interest in parenting me, especially as I got older. My Mom talked me into having his parental rights terminated when I was 13. It wasn’t difficult–all I had to do is write about the drug use, him dragging me to the bar every weekend, and his heroine-addicted girlfriend.
I didn’t talk to him until 10 years later. I was 23. I just called him up on the phone–he was living in the same place–and asked if I could come over.
I wanted to see him because I was about to get married, I was an adult and I felt like it would be okay. And it was okay. He’s still an alcoholic with no driver’s license and he’s not as sharp as he used to be. Things were really awkward at first because I had to explain to him everything that’s happened since I last saw him. We were strangers to one another. A lot of it was pretty hard news to bear, in part because deep down I hold him partially responsible for it. By not being there he failed to protect me and all that. On his end it was awkward because he was absolutely devastated by losing me. He’d lost both of his sisters and if anything his tragic life had made him more and more determined to remain an alcoholic.
I love him, but I don’t feel any particularly strong feelings about him, not anger, not even sadness really (or at least, if there is sadness, it’s a really dull sadness.) The only thing I feel on any kind of significant level is guilt, and it’s the same guilt I felt as a child. There is nothing in the world he could do to make up for his failure to be there. I call him Dad, but whatever feelings are supposed to be there just aren’t. We enjoy one another’s company. I visit or call him every couple of months or so, talk his ear off for about ten minutes, and that’s it. But I’ve come to accept him for what he is, to enjoy the time we have together for what it’s worth. I feel like I’m there to make him feel good more than for myself. He’s had a hard life and I just want to ease some of his pain by letting him know his daughter loves him.
I’m telling you all this because I think in the case of an absent parent it’s easy to drum up this idea in your head about redemption and having them back in your life. But the truth is the past is over, and that emptiness you feel, or whatever it is you do feel about the situation, is not going to go away. If you think you can find a place for your mother in your life now, if you think either of you might benefit from such a circumstance, then by all means, go for it. But if you are hoping for the Mommy you never had, the relationship you didn’t get, you’re going to disappointed. She will likely be the same Mommy, have the same flaws, just as my father has essentially not changed at all in the decade I didn’t see him. What you got then is what you’ll get now. The difference is, you’re a grown-up now and you don’t NEED the same things you used to. Maybe now that you don’t need a mother, the mother you do have will fit nicely.
Whatever you do, don’t feel guilty about your decision. Just do what you need to do to be healthy.
I also wanted to add that I don’t know what your mother wrote to her mother, but even if your grandparents have been nothing but nice to you, it doesn’t mean they were great parents. My grandparents are like saints to me, and my grandpa is the closest thing to a father I have, but he was abusive to his own kids and succeeded in screwing most of them up for life. I don’t know why my grandpa was safe for me and not his own children, but if they were bitter I sure wouldn’t hold it against them. Again, I don’t know the situation, but it might help to take into consideration the possibility that your mother had every right to write what she did.
