In February of this year me and a cousin fell out and stop talking. The reason we stopped talking was because she had her first child and two weeks later I had my second child. she became demanding that I go see her first child and with me just having my second child it was difficult. It's not that we wouldn't have seen her first baby it was the timing of her expectations for me to see her first baby. By the way she lives a two hour drive away. I assured her we would get a date in. But she continue to demand to get a date in soon. Anyway in October of that year where we both had our children , it was my brothers wedding. As I knew we would be seeing and meeting my nephew at the wedding for the first time I specifically went out and got a few gifts for him. When I gave the gift to her at the wedding she later told me that it 'was a can't be arsed gift'. Because I didn't go to see her baby and gift the gift then. I should add she posted a gift for my daughter and I honestly I still appreciated it. I didn't expect her to come to see her. It's the thought that counts. I also told her we were planning on coming up that summer as I was finally getting to a place where I was comfortable in myself and the new family dynamic of having two under the age of 3. This wasn't good enough for her. She also continued to compete with everything I did. And I found her exhausting.
Anyway enough was enough so we had a confrontation in January of this year and we haven't spoken since.
Now this is where I'm struggling. So we have an extended family WhatsApp group where occasionally we wish cousins, aunts and uncles etc happy birthday. Today was her birthday. I of course I wasn't going to wish her happy birthday as we don't talk. My husband did. This is where I have an issue. Because although he agreed that how she behaved previously was wrong and that he didn't like her he wished her happy birthday. I told him by doing that you don't have my back. He did take accountability and apologised. My issue is he's done this before. He said he only wished her happy birthday because he thought her husband wish me happy birthday (which he didn't nor did my cousin).
I'm struggling to forgive my husband even though he's apologised it's because he's done this previously. Where he has put others before me. I'm I wrong in this situation? I know it sounds silly but it's more the principle behind it that's getting to me.
