Agree with mak in that you have had one mega year...super busy, pregnant, baby, new life changes all around...including the BIG one...moving to a new town. that is a really big one. and i guess that now that you DD is just that little bit bigger and less newborn-y you actually have more mental space to actually think about yourself in this new life and are trying to discover your own path that isnt intimately connected to creating a safe place to have a baby ITMS....now that life is getting more settled and normal it is now imperative to seek whether that is the normal you want ITMS. I reckon that by listening to your discontent, although challenging in how it raises insecurities, you could grasp the Big Meaning of it and trust that it is telling you to do some navel gazing and begin to set out a path that you want to walk. take this moment of free-fall as a sign, your body and mind telling you that things arent right and need attention...planning your next life stage could offer some wonderful opportunities to remain true to you!

I'm worried that the new town is not going to be enough for you home is where the heart is and the heart needs a home. Raising babies in isolation is not the way we roll. I think that this has to be the most important thing to begin working out ways to rectify. you need the love and support of a wider range of contacts - otherwise the pressure placed on your relationship with DP will be the be all and end all and that can be extremely challenging (I have BTDT...it works but isnt always anywhere near fun).
I am assuming there are no people to gather even an informal mothers group? Could you ask around? even if you can connect with one other woman with kids it can make life so so much more beautiful and less intense: cups of tea are amazing when shared
