I am trying to help my fiance. I bought a couple things for his daughters easter basket, and it's like he doesn't aknowledge to the grandma I help him...I have told him countless times I am willing to help yet he still acts like I can't or don't do anything about it. I think that's why she's been a bitch since he told them I'm pregnant..honestly I can't figure either of them out...I'm getting fed up with trying...
