my sons girl friend says i have to do it her way?

I have a 2 year old grandaughter my first grandaughter .. Ever since I met the girlfriend 3 years ago she has always said I didnt like her . I have told her many times I do like her . She had my grandaughter 2 years ago and when she was pregnant I was told I couldnt buy the baby's first anything .. The crib was a mother daughter thing and everything else was her and my son .. I said ok and understood that .. Well she has a baby shower and I bought clothes and toys and gave her a card with money to go shopping with me . We went shopping .. she bought what she wanted. Well Now after 2 years she told me that Bought nothing for the grandaughter .. I explained I was trying to do what she told me to do and not step on her toes to buy anything of the first.. She said I was a horrible grandmother and do nothing for them. She is 18 now and my son is 19 they live with her grandmother . I have bought 1000's of dollars of things for this grandaughter since she was born . MOm says I dont do anything for them .. I have helped buy them a truck and paid for my sons auto insurance every month now for 2 years. to help out in December alone and not for christmas present I bought him 600 dollars worth of tires for the truck . On Thanks giving day the girlfriend had to work and I asked my son if he could come over with the baby I had not been aloud to see the baby for a month and the girlfriend said no .. That he needed to stay home and help her grandmother with thanksgiving dinner .. I have to tell you buy the way I have never been able to keep my grandchild with out her mom there or see her the girlfriend said that i have to come over to their house to see her and play with her in her room .. There are 10 people who live in that house some of which are not the type of people I would want to be around . Any way I got mad about the thanksgiving thing and finally after 2 years told the girlfriend she was not welcome in my home anymore.. I am fed up with buying the girlfriend things explaining to her i loved her and feeling like I have to buy them things just to see the grandchild . Well christmas came and many phone calls from the girlfriend cussing me out and my son calls to see if the girlfriend can come over for christmas ..I was appalled .. but despite our difference I told my son I had not bought anything for the girfriend and It will probably hurt her if she came .. I had bought for my granddaughter though ,, He told me she is fine with that just wanted the baby to see her grandmother on christmas I have to other sons and their girlfriends and babies were there tooo they got a lot of gifts and the girlfriend went home crying because i Had not bought her anything.. I did give her a gift that i had bought extra in case someone did show up announced like a friend or something.. I gave it to her .. was not good enough she was upset because she saw what the other girls got .. anyway we had a conversation yesterday and the girlfriend told me it was my responsibility as a grandmother to buy things for them and the baby and i shouldnt be whinning about paying for the insurance for my son and buying the tires because he is my son . That I should be greatful to do these things because I make good money .. She thought she was better than a bath and body works gift basket.. She said you cant expect to treat me this way and see your grandaughter... I am soooooooooo confused.. She thinks I have to buy things for them .. I explained to her I am not responsible to buy things the things I buy are out of love.. She said no you are the grandmother u are sopposed to do these things .. I am appalled and dont know what to do

Stop trying to buy their attention and affection. Sorry but you raised a son without a backbone.
