I'm so done with my fiance family. They can never come visit our kids or show up for any party we have for them. His one sister shows up for everything for the ones sisters kids but doesn't even call to wish my son a happy bday. Then my niece rubs it in my son's face about getting gifts and everything's from the aunt. I know it shouldn't bother me but I hate my son being so upset about it. My one sil decided to have our nephew a little birthday party today and didn't even tell us. She calls my fiance up asking if we're coming. He has work at 4,the roads are bad, plus we don't have the funds to drive an hour away and to pay for all of us to get in the place. We just talked to her about it last week and the extra money goes to what we need for the baby. Then she asks my fiance if I could come and when he says the roads are bad she has his uncle call not to long ago asking if we're coming. She's so selfish almost all of the time and then she comes to us saying she can't pay her bills and is behind. Sorry for the long vent but I needed to let this out to someone other then my fiance
