Romain also could have made the effort and came to LA more often knowing that I was going through a tough time in my career/life. He could have understood that I was not being myself and just needed him to be there and emotionally support me through this tough time instead of looking at cowardly ways to get out of the relationship and leave me. I believe if you love someone, you do everything in your power to fight for the other person and not let them go.
However, no matter what I did, there is no excuse that would make the flirtatious emails OK. If I forgive and forget, will I trust him that this won't happen again in the future whenever we are in a fight? I won't make excuses for myself, and I definitely don't blame myself, because it takes two people to make a relationship successful or fall apart. But I am also not the easiest person to deal with, especially if I have issues that I am dealing with in my life. I close down and don't want to be around anyone. I am glad that I cooked Romain a nice dinner to bring this up to him and found another approach to deal with this, rather than calling him and yelling at him and moving out, like I would normally do in this kind of situation.
Time will tell and hopefully will heal the pain.
