Why didnt he tell me?

I ended up hearing from my Brother in law (he didn't know that I didn't know) that he, my husband and husbands coworkers were going to play soccer tomorrow Christmas day. the thing is my husband did not tell me this. he claimed he was working Christmas day. I feel hurt that he made plans and hid them from me when he expects to know what I'm doing. when I confronted him via text he got mad and claimed it wasn't true and that he was working. he later admitted that it was true. I just don't get why he would not tell me and lie about it. it makes me feel like he's been hiding more stuff. I don't care if he plays soccer but why lie? I feel like I'm overreacting
