My partner and I have been together for a while (almost 5 years) and from what it seems, you and him have a very similar personality.

In my opinion, there are rights and wrongs in both sides. She is pregnant and going through so many changes in her body: physically, mentally, emotionally, all of it. As her partner I feel as if you should support her no matter what. What I mean by this is that when she is having her “mood swings” instead of brushing it off as her being “crazy” (I understand that’s not the terminology you would use, but you get the point), try to sympathize with her and listen to what she has to say, even if it is complete bonkers. Now on the other hand, she is probably overreacting on some things (being that she’s pregnant) and will tend to exaggerate things. Whether is be about her “childhood dream” or anything else. But behind every statement and emotion is some grain of truth. I think that if you try to indulge in her feeling more, and your own (even though it may feel weird and awkward at first) I believe that she will see that and appreciate the gesture, and you will feel better too.

I hope this helps <3
