I'm upset that my boyfriend keeps going on international trips to visit another woman
When did you figure out that there is another woman involved?
At the beginning of the summer I found out he was going on the trip.
I am sorry you found out that your boyfriend is cheating on you. It would be best to break up with him if you don't want to be with a cheater, even if it is painful now.
I will break up with him but I need a few days to break down.
I do not think that you should delay it any longer. I do not think that it is okay what he is doing, he should not cheat on you with another woman.
