Love triangle... in a way

My marriage has already ended long time ago and we are both not doing much on saving it or ending it. But I am not going to talk about my broken marriage. It is about this 2 guys I met online. One guy I've known for 4+ years, he is miserable in his marriage and stays about 9800 miles away. There is no way we could be together, but we were there for each other through our darkest times. About a year ago, I met another guy online (4500 miles away). It started off decent and nice, and then some sort of feelings developed. We met in person about a month ago, and it was the best meet up ever! We had so much fun and he decided to meet again somewhere end of this year. I saw his efforts. He is working extra hard to save money etc. Now the other guy (9800 miles away) is struggling to accept the fact that I am seeing this man. I feel so stuck and guilty now. I am not sure if I should focus on this guy as he was there during my darkest time or with the new guy who is making the effort to be with me. And yes, I am not thinking of my husband since he is the reason I am in this mess.
