Emotional

Myself and my wife have been trying for years to have a child. We had one positive outcome, when we went to the doctor it showed nothing. My wife tells me to find someone else because she is having trouble getting pregnant. (Now mind you is absolutely a little harder for 2 women) not like we aren’t trying. I get a little sad when I see someone else able to have a child and we struggle. Yesterday her sister says she pregnant yet again.(already has 5). How am I suppose to be happy for her when I feel like she kinda rubs it in my face. I swear all she does is open her legs and boom she’s pregnant. We want kids so bad and we see people all the time in news stories who beat and kill their kids for no logical reason. I pray to have a child and some can’t even take care of one and take them for granted. I love my nieces and nephews but I take care of them more then their own parents. 🙁 I wish we had a small bundle of joy for once and not her sister. Is it wrong to almost sound bitter?
