I've realized very recently that I need some advice with managing how I react/act with my significant other. I have a hard time navigating this particular subject and so I seek the advice of strangers....

The situation is perhaps larger than this, but the gist is that we have entered sort of a new phase of our relationship (we've been together 11 years) and it does involve us being in an open relationship. I'm chalking a lot of it up to me being pregnant, and I seem to be having a certain amount of FOMO and slight jealousy with my wife spending time out of the house (on top of her working a lot). How do I regulate how I'm truly feeling (which is honestly fine with our situation) and what my irrational thoughts SAY I should be thinking... if that makes sense. I know I'm affecting her mental health and it's not healthy for either of us. There can be some give and take on both sides, but I do recognize that I'm the one that needs to figure out how to manage my side of the emotions.

Feel free to ask clarifying questions... not sure how much sense I'm making :)
