My DP is happy that we are TTC, but he doesn't get why I chat on BB website and chart my cycles either.
We talk about babies and pregnancy, but he has to be in the mood for it ( make sense ).
I do just think that women take more interest because it is our bodies that have to carry the baby. We lost a baby at 15wks last year and while I was pregnant, my partner really took more of an interest and was so excited. I think that because your partner has agreed to TTC, he will get more into it when there is confirmation of a pregnancy and your body begins to change.
I wish you all the best..
