You are ridiculous. You were the one who approached me, who told me we were family, so obviously it matters to you. Hell, if you'd have come just to accompany Wanda (who I've known just as long as you), that would have been fine.
Shit, I've talked to you longer than I talked to the man I was marrying, so don't tell me that we're not close just because we haven't known each other long. If there is a lack of bonding, it is because one or the other of us hasn't tried.
Regardless of what it is, she might like to hear from you. For some reason she loves a version of you, and this is the sort of thing that family exists for. Whether you think of her as family or not, she sees you as such, and would it fucking kill you to talk to her?
