I know how you feel. I have done so much, picked out daycare centers, kept notes and calendars, got all the stuff together for the custody trial, remind
DH of CS pymts. I make appointments, and am usually the one to take the kids to see doctors/ dentist. I usually take them to practices, although DH almost always meets me there. I guess a lot of the stuff falls on me b/c my job is much more flexible, and I'm more organized.
I remember for a while, it was hard not to get my feelings hurt when I was left out of all parenting decisions for
SS. He would talk over stuff with
BM, or tell me that it was something that they had agreed on when they were together. I let it go in the beginning, b/c SS is their kid, and who was I to try to step in and act like I had a say so.
We had to rethink all that when DH and I had a son together, b/c it wasn't fair to have a different set of rules for each kid. And I surely wasn't going to relinquish all parenting decisions to DH and his ex when those decisions were going to affect my child.
Now DH is really good about consulting with me for most everything. Sometimes he lets BM know he is going to consult me first, sometimes he just tells her its something he needs to think about. There are still somethings we don't agree on, and occasionally, we do have to change the rules depending on the kid. But for the most part, we try to make it work and we try to work together and we keep everything as fair as possible.
It is hard though, b/c BM loves to remind me that I'm not SS's mom even though I'm more involved in taking him to appointments and school stuff than she is. And I see it passing along to SS who will remind me (not all the time but often enough) that I'm not his mom and I wasn't around when he was born. I've been there since he was a year old and it kind of hurts when he comes home and tells us "I've got a new dad" talking about a stepdad (he's done this twice now). I guess if DH and I weren't so HUGELY involved in his life it wouldn't sting so bad. We were so careful not to refer to me as mom, and SS tells us his mom told him to call each of his stepdads "dad".
You don't want to be put on a pedestal for what you do, but you do want to know that you are appreciated for all the stuff you do. Being a stepmom is hard, you do all the same "work" of a parent, but don't get any of the glory.
A suggestion- start sending gifts from you too. Maybe you could send pjs from DH and slippers from you. Think of things you have in common, like if you both like ladybugs, send her some ladybug stationary. If you both like a certain band take her to a concert. When she comes to visit, tell her what areas you have experience in, and tell her if she wants to talk about it you'd be glad to share. Mention your concerns to DH, b/c it sounds like he needs to make some changes as well and he may not realize that he is leaving you out in the cold.
