What do you feel when you know that your lover falling in love

Phew.. this is a tough question. However, I will try answering it as best as I can. To me if I found out that my love has fallen in love with somebody else, I would feel very disappointed. I will feel as if I have no future to look at. I feel as if I have lost the most precious thing. If I know he is cheating on me, I would be angry of course in the beginning. But maybe after a while, I would really sit down and think about the reasons behind all that happened. And i will surely have a deep heart to heart talk with my lover. After resolving all issues that might come up, we'll try to come up with a solution, and a final decision. And after that I will try to accept the decision in my life.
