Hurt by My husband on Mother's Day!!!?

My husband said, "Sunday is Mother's day and I am going to spend the day with my mom". I was really shocked by that. Years prior he would see her for breakfast or brunch or not at all... A few minutes later asks what kid he can bring out of our 3... I said none its Mother's day they will be with me.. Mother’s day comes and that morning he gets up early runs to get coffee, flowers and a card for me. He comes home as I am doing dishes and feeding my three children breakfast. He leaves and goes to take his mom out to Breakfast/brunch. His mom is not in our life ever (her choice), she is not apart of her grandchildren lives, she doesn’t want to be… He tries so hard to be in her life and wants her to be apart of his children. She just doesn’t have any interest or time… SO, Mother's day my children and I spent the day together. Having 3 childrren 10 months, 6 years and 11 years is no easy task… On Mother’s day I tried to have a good day for them by taking them to the park, making them a nice dinner all while I was very hurt inside. I am watching other families have a great Mother’s day and I just felt so hurt and alone. It really hurt to see other moms and dads having a great day with their kids. I truly felt like a single mom.. Am I wrong for feeling this way???? He called at 4:30pm asking if I wanted to go to dinner with him, I told him I was already making dinner for my kids and I… He gets home and I am not talking to him, he told me I need to grow up and get over it! Its not a big deal that he went to spend the day with his mom… AM I justified for being hurt or am I taking it to far? I am still hurt on Monday that he didn’t want to be with me, try to make me feel special, show any interest in me!
