My boyfriend still accepts gifts and food from ex wife?

Me and my boyfriend got together a year ago and him and his wife seperated a few years (about 3) before that. And she still makes him food and buys him things from stores. Now I got upset because to me it's disrespectful to me because I'm his girlfriend and she's his ex. Yes I let them be friends because they have known each other for about 16 years. And I've tried to let it all slide. But when she found out I was cooking on Thanksgiving she made a whole other ham and gave it too him as well as banana pudding because she didn't want him missing out on her Thanksgiving and how she thinks my cooking isn't good enough. And even his 14 year old daughter has said what her mom did was messed up and not right. And I confronted him about it and he told me that I'm being childish and immature and that he doesn't understand why I'm mad. Am I in the right or is she in the right? I'm just confused. And yes I am younger than my boyfriend by 10 years
