What a terrible thing to be going through. I can honestly say that I have no interest either. When it comes to bed time I just want to sleep! I work full time and also take care of horses and also am pregnant and at the end of the day it is the one thing I am not always interested in. Most of the time I will give in occasionally and that is just to make my partner happy and then he can leave me alone for another 2 weeks I am very lucky that I have a great and understanding partner so If I say no, he will not get to upset or angry. I am also not very affectionate because I really enjoy my space but occasionally I will like a cuddle and it always helps to show some affection back even though you may not be feeling like it. I try hard even though I tend to be a bit grumpy and naggy all the time.
