Talk with your man before you accuse
My boyfriend is showing less interest in me since we moved to Beijing from the United States. Is it a sign he's cheating on me?
Women split from men because they're unhappy in the relationship; most of the time there's no third party involved. Men, on the other hand, almost always separate from their partners because they're involved with someone else. You both made a significant commitment to each other by coming to China, but if you feel insecure about your relationship you need to bring it up with him in a non-confrontational, non-accusatory way. If his work commitments are such that he can't spend as much time with you as before, get involved with other things. But if there is solid evidence that he's cheating on you, investigate it discreetly and find out the truth.
My girlfriend and I have always had heated arguments, but lately our fights have turned physical. We're both in our 30s. We got together in Beijing almost a year ago. Is it time to break up?
