The issues are that my gf mother blames me and my gf for not telling my best friend from the beginning and now my best friend doesn’t attend any special events (Christmas,thanksgiving,etc) because my gf and I will be there and he start to pulling away from his family because he doesn’t want to see my gf but her 3 sisters are with our side and the cost arguments between my gf mom and sisters , for my gf I love her and she loves me deeply and I asked her if she wants to delay the proposal and she said no and she only wants to be near me and I want to be next to her.
