Exclusion efforts

My fiance and I blended our families a couple years ago, and I have treated his girls as my own and stood by his side supporting him through a nasty custody battle, even through attempts of his exs to try to make me out to be some abuser to CPS in order for her to get her kids back. Even still, I have stuck by them understanding abandonment all too well from my own life. As of recently my fiance has been doing everything he possibly can to make his kids feel more important than us. Like so blatantly disrespectfully, its just cringe to me. I planned a trip to Great Wolf Lodge for the girls as Valentine's Gifts, and they're doing that alone now on Wednesday. Yesterday, he took them to a pro soccer game, of which is something I showed him since my daughters play soccer and baseball. He hasn't played with his kids for almost the entire time we have been together regardless of my encourement efforts, and now he's out in our in the neighborhood excluding my kids, playing his self entitled "all around awesome dad" role. And just last week I caught so much shit from him and his family for simply posting a picture of me and my kids when we went to a wild sunflower field and I captured beautiful images of all of them together (excluding myself).
