I need help to get my revenge

Two years ago I met a guy online, it was only sexy videos without face. I go MIA but back in January I became single and decided to get back on the old Snapchat. Where he messaged me often but since I was not on it I didn't see the messages. I decided to reply and he was so happy to hear from me again. He is from Germany and I am from America. In March we started having contact everyday & we decided to finally fully reveal ourselves. He was way more handsome then I could imagine and when he saw me he was just as amazed. We start video calling everyday and staying in touch. After a month he asked me if I could only be his and we can make it work by visiting each other etc. I agreed and everything was going GREAT! He made me feel like I was the most beautiful girl & I loved everything about him. We understood ech other so much... In June he's father gets sick and he has to go back home with his parents. At this time he was someone who is avoidance to attachment and fears it, but something about me he said that made him just be better and want to express himself. But two weeks being at his mom's I notice he became a little off, he said everything was good and he was ready to go back to him home so he can be comfortable talking with me. In July he goes back home but after a week he ghosted me. We were video calling and he just disappeared. I got so worried cause he was not answering anywhere so I contacted a friend from Germany to help me make sure he was okay. She located him and he said he was so sorry, that he's father got sick again, & everything he is feeling for me is very overwhelming. He wants me but can't have me . I felt like maybe me being Hispanic and him German he probably can't see us becoming a reality. I told him I understood he could have told me & we could have left it at that. By the end of August he is back to his you make me so happy I want you and I can't wait till we see each other. I recently called him to confirm days for Germany and he's face expressions were different like he was sad but couldn't speak. I asked him what's wrong he said nothing. I said is there someone else? He said no but I could tell there was. I asked how long have you been talking to her and he said a few weeks. I am so heartbroken because I fee like this man has played me but his actions and words say he wants me but feel like someone around him is maybe telling him no... Point is I am not still booked to go to Germany in January and I want to get revenge on this man! Idc if it's me knocking on his door or putting up a billboard of a piece of shit of a man he is I just need something!!!
