My fiancé and I have been together 2 and a half years. He has a child by someone else. I love this child like he's my own but his mom is driving me crazy!! She calls at 1 in the morning for idk what! When the child comes over he's not clean and he stinks. So I bathe him and make sure he gets his homework done. Just last night she called him to see if he could take her out of town or if she could use our car.... I feel as though she has her own responsibility and so do we. The child is the only mutual responsibility that we share.. She doesn't respect us. My fiancé is very calming and relaxed so he tries to avoid any negativity. I've told him that there's boundaries that need to be set but every time he says something about it she start to fuss so he leaves. I'm just really tired of this and it's going overboard now.
