Thoughts on this wedding?

So my boyfriend of 6 years and father of my child was invited to his cousins wedding which happened last weekend. He was invited but I was not, his cousin stated that due to Covid they had to only invite close family and that was it as they had a 50 person limit. The wedding was in BC so it was a nice little weekend getaway for him and his fam. I was totally fine with not being invited as I understand with Covid that limits on gatherings were low. But then I found out that his brothers significant other was invited, she had a place setting and everything. I know this because of the photos she posted on Instagram. I just feel a little left out now and possibly like maybe they don’t consider me family or something. If she wasn’t invited then I wouldn’t feel bad at all but because she was I do feel a little left out. What are your thoughts?
