Do you really have to travel? it amazes me that you already know the potential risks that may come up with your travel and the proceed on to consider travelling.
You have said something which people are not cognizant of. With the Trump administration coming in, it's not going to be business as usual. Extreme wisdom and discretion is needed.
So let me get this one straight.
1. The amazing boyfriend was coming from Australia to visit his amazing girlfriend.
2. The amazing boyfriend has another partner in the US and a WIFE back in Australia.
Life is so unfair. One person has 3 partners while another person can't score a one-night stand let alone a partner to save his soul? lol.
You: " I met an amazing woman in brazil. She is everything i prayed for for 35 years..."
Her: " Finally heavens has opened the door for me to go to the US"
Lol Am I communicating?
If the charges were dismissed, then you are good to go. Might be a delay but you will be fine. Make sure though it's in fact a dismissal and not a pre-trial diversion ( look carefully your documentation) coz that may be tricky
