I would be somewhat conservative about the seriousness of the relationship. In reality, you have no idea what it will be like when you are together, so be open and honest with the border security that if it doesn't work out, you will leave (if they ask).

Agreed also that your friend and his immediate family should be prepared for a phone call from your first port of entry if there are any concerns raised by CBP.

As every indication is that you have honest intentions, honesty is the best policy. You are the least of CBP's concerns. If you don't, then they will likely see through it (as they should).

Enjoy the USA and best of luck to the two of you.
