I don't know how to feel about my In laws

So my partner and I have been together for 5 years and he introduced me to his family after a year. For about six months his mother seemed to like me however since we moved in together things changed.

She no longer talks to me when I am at their house. Not even a Hello, how are you.

She will wait for my partner to visit alone to discuss anything important which generally impacts my life more then hers and then wonders why I get annoyed at being left out of life decisions that affect my future.

We told them we are buying a house and they didn't even acknowledge it. Yet the next time he was there alone they wanted to know about the house he was buying.

When we told them I was pregnant they said "oh" and promptly changed the subject.

They never ask how I'm going or the pregnancy is going.

We went to tell them what we were having and they simply said "I don't want to know" but want me to change my baby shower to be gender neutral when I have planned it all in blue because I am so excited for my boy.

I feel like they really don't give a damn about me or my baby and I am nice to them when I am around them. but they just make me feel so unwelcome and like I'm always intruding.

does anyone else feel like this?
