:yeahthat: all of the above.

Can you try & explain to him what is going on here... you are growing a baby, it's a huge toll on your body! maybe give him some reading, pregnancy books or the like that can explain what you are going through (and what's to come for that matter).

He needs to understand he is not going to have you at his beck & call for a long long time to come... better to sort it out sooner than later.

Hugs to you It's a time of adjustment and I hope it passes soon for you and you can move together into the next phase of your relationship.

ETA - just thought I'd add, it's worth keeping in mind I guess that it can be a stressful time for men emotionally as well, sometimes the idea of another person to care for & feed etc is a bit daunting in the beginning.
As Traveller said, you need to sit down & talk with him about how you are feeling & it might be an opportunity for him too if he's feeling a bit out of sorts.
