<human>: I'm getting married to my fiancé in February. We've been together for just a few months so I haven't had the chance to meet most of his family yet. One of his female cousins texted me this morning inviting me into her family. Text below: hi TheTinyGirl! I've heard so much about you and excited you're going to be part of our family. I know it will be overwhelming to come to our nut case family but please don't hesitate to let us know if you're uncomfortable. Hope to see you soon. 

The problem is I'm not at all social and extremely dumb when it comes to relationships of any kind and I have absolutely no idea what to reply. Help me reddit!

Can you condense the text into three sentences or less?
