Thank you so much for your responses. I'm still going back and forth on whether his decision to cut his visit short was based on malicious intentions or not (he said something to my sister that put more evidence back in that category) but regardless, I think this:
Perhaps your dad will be the best grandfather he can be even if he isn't the best grandfather you wish he could be.
is very true regardless of the nature of his motives and abilities, whatever they are. And it's so true that even if his availability and choices as a grandfather (and father!) are disappointing, I will be okay. I would like him around more, I would like my kids to see something of what I saw in him as a dad, but you know what, if he's not capable of that, I will share other experiences with my kids. It's just sad and I can't really believe that my kids will have such limited access to my family and my past. My siblings are still an important part of my life but my parents have both just taken themselves out of the picture and I really never thought that would happen. As tumultuous as our time together as a family was, I just can't believe they would pull away from their family, especially at a time when it seems to me, people get the most benefits out of their kids! When kids are young you have to work hard to take care of them and sometimes have little left for yourself - they put that time in and now that it's time for them to be the ones that are more taken care of, in a relationship that's more equal, where they get to just enjoy the grandkids and enjoy the visits and not really be needed as intensely, NOW they can't handle it and withdraw? (I mean my mom already did, but for her also it was when we were teenagers, not babies, that she left our family). It's so weird, it feels like I worked so hard as a kid to prove myself responsible and adult and that I could help out because they were overwhelmed with responsibilities, and now that I actually CAN, they distance themselves? As hard of a time as they had dealing with my needs as a dependent child it seems they have even more trouble dealing with me as a responsible adult. I guess I still have my own needs, different from theirs, which frustrates them, but now I also have the ability to make sure those needs are met, with or without them, and if I am going to meet my own needs I am going to have less of them in my life because they have so little to give. (Though I do think what I am asking for is pretty limited - just some of their time, and some personal space with my new babies)
I will try to just do this
the best advice I can give you is to try to relax and let things happen between you and your dad.
I certainly can't change his behavior or his view of his role as a grandfather, so I will just try to be gracious during whatever limited time he is around. I am so used to putting in all this extra effort to make sure he is there for me when I need him, and I'm changing that behavior because I have these new responsibilities, so I guess that is what is stressing me out. I'm worried that without jumping through all his hoops he simply isn't going to be there and in fact that does seem to be the case. But going back to what
Pilate said, even if he isn't there the way I would like, the world will go on, I'll still have my sweet new family to focus on, and everything will be okay.
It's just so hard to let go of trying to make this relationship go the way I want it to... .
