To be fair, the OP said whenever the work was cooperative the person said "We", not "I", which I think is an improvement on snake. I'm not saying it's great, but it also sounds like the OP needs to be more proactive about speaking roles in meetings when it comes to value of their practices, why things were done, etc. Now, would I work for a person if I hated them? Nope. Would probably be out of there. In terms of "How can you!?", this stuff happens all the time all over the place and people work together. I think you can work through it with colleagues - it's not easy, but it's important if you think the mission / company are worthwhile. Otherwise, you're just going to dig deeper "into the box" on the credit thing and it won't be a good reflection on your work.
