What do I do

I received a letter from my mother who I havent saw for 6 years. I have been intouch with her on and off since i came back from living abroad 4 years ago. I lived abroad for two years and when i was intouch with her out there and i was very depressed at the time and said about coming back home as my mind was all over the place and very upset on the phone to her, i gave the phone to my husband and She said, was i mental to him. i cannot forget them words there was no supporting words whatsoever but she did apologise eventually but it always stays with me. She as put in her letter, dear then my name, some money for the kids all thou you dont keep intouch, I dont know if thats something to do with your brother, then she goes on about my cousin having a baby, looking after my father, her going on holiday with my sisters and at the end of the letter saying, I hope you are all well, the children must be big now, let me know if you got the money. She sent £30 for three of them. My brother whom she mentions is someone I dont like and dont keep intouch with, he as always thought he was better then anyone else. I sent her a letter a while back saying what my kids are doing but theres never a reply with im glad there doing well, glad thry like college, nothing. I feel shes not interested and only wants to talk about whats happening with my family who I have no time for. I dont know if to return the money as she is a pensioner and I dont like the way she started the letter. I want to reply but dont know if to just talk about my kids or not mention them and what to put ,

She will always be your mother. You only get one really. You need to understand that this may be all she can do. This may be all the love she is capable of showing. She did think of you when she wrote the letter and sent the money. Love her for who she is and understand that with family sometimes we don't get the love we feel we want or need, we get the love that they can give. She apologized for her rude words. She cant take them back. She is trying to keep you in her life. And because you do not like your brother does not mean you mother with dislike him. He is her son. she will always love him. I would encourage you to keep a relationship with your mother. Don't close her out. It sounds like you two do not live close anyway so it doesn't sound like it would be too difficult to say a few kind words to her now and then.

Do I return the money as my children are 16 18 and 20 as she is a pensioner, do I just tell her about what my children are up to and not mention about my brother to her and what do I say why I dont keep in touch?
