Dear Fitnik
I am at a loss for words...my heart feels heavy for you and your situation. While I am not familiar with your cultural background and, thus, all else that factors in to this, I can't help at being perplexed at the lack of comprehension of your husband for that ramifications of this situation...even if you weren't pregnant.
Pardon my ignorance yet desire to help...any chance that if she is not working you and your husband could utilize her as FREE childcare, housecleaner, cook, etc. - anything whereby it might help her "earn" her way? I'm trying to be realistic as she will have had her own first child but none the less, women have done what seems impossible when there are not other options.
I love my DH who I think is exceptionally sensitive yet every once in a while he shows a level of ignorance that makes me question his ability to walk on two feet instead of all fours.
I don't know what to say except that I will pray for you and your family and PLEASE try and focus on the amazing experience that you are about to embark on. Also, it will be interesting to see how your DH's perspective may change when your SILs child is born. It may shed some light and the idea of TWO young children in the house, one of whom isn't his, may be overwhelming enough for him to make some changes.
Please keep us posted and know that we are hear - even if only to listen.
Your friend in fitness, TAMMYSPQ
