Visiting!!!

So, I've been with my long distance boyfriend for almost two years (will be two years July 19th) and I haven't met much of his family because they aren't as close as my family is. My boyfriend got the weekend of his birthday off so he could come visit me the 25th and 26th and I found out his mom is coming up too! I've never met her before because she lives even farther away from me than he does, so I'm kind of nervous and excited. Any advice? This is my first long term relationship, as in more than a few months, and I really don't want to mess anything up 😅 I'm really hoping I get along well with her
