Am I over-reacting?!

Sarah

I'm currently 5weeks pregnant and my partner lives with me. At the moment we are looking after his almost 3yo daughter which can be very full on at times. Today I came home from study and just wanted to be left alone to have some 'me' time.. he cracked the shits and now I feel guilty/bad for wanting that.. I should be entitled to have that, shouldn't I? I don't want to be stressing out especially whilst pregnant.
