Birthdays

On the eve of my 51st Birthday, I realize that they just aren't special anymore. My ex makes the biggest deal out of delving out money to my daughter so she can buy me a small gift. Should I take money from his child support and give it to her to buy one for me? Should I take her shopping also? My mother, bless herself, always made a big deal out of my birthday. She told it was the ONLY day of the year that was entirely yours, and you earned a good time. She told me Happy Birthday on the phone today while I was at work, I said it's tomorrow Mother, she said take it while you can get it.... lol .. I had planned to do something that I really enjoy tomorrow, but my mother's son is appearing at her house, which happens to be my house. She is worried she will have to talk to " those people" without me. With her dementia, she rarely initiates or carries through with conversations with other people around. She simple sits and smiles as if she is already visiting dementia land without us, which is simply not the case.
Happy Birthday to me, I'm thinking I will get a cocktail somewhere during the day to appease my selfish thinking that it should still be a special day. Cheers!
