She’s pregnant and hormonal as fuck.
You're going to have to get used to this shit for more months before she levels out. Then, prepare to be ignored, as baby will come, and that’s all that will matter. Then, prepare for “you can’t do this right, so how can I expect you to take care of me/family” bullshit. Then, after that, if you haven’t killed yourself, left, or died, she sounds like an emotionally high maintenance person, so constantly having to prove yourself to her will get stale and annoying.
All this to say, GTFO, man. You’re not ready for that time bomb yet.
TL;DR: Lace up those running shoes and make like Usain Bolt.
