Welcome to our forum.
Just be "prepared" (which by definition you can't) for whoever comes into your life to be a unique person with individual wants, quirks, needs, and circumstances. They might already have a partner, kids of their own, etc.
There's lots and lots to learn on this site, so have a look at our various threads, and post any thoughts, concerns, or questions you may have.
Glad to have you with us.
Love means never having to say, "Put down that meat cleaver!"
