My mom simply dislikes my boyfriends mom for the fact that she has to share her grandson w/ her. 😑 like I understand this is my mom’s first grandchild. And my boyfriends mom is very involved w/ my pregnancy as well always wanting to come to doctor appt’s etc. I love her just as like she was my mom. But it’s so annoying how my mom always has something to say about “sharing” my son w/ his other grandma. 😭 my mom just wants him all to himself 😂
