I think i fall in love with a man.

Being on a third-party situation is avery sensitive issue. One can never tell if he or she is already trap on it. Maybe you're just admiring the man. If he has a girlfriend, then that's your call, your choice. You can do some flirting and maybe would be able to win him. BUT. That really all depends on you. And to your level of conscience. Love is complicated enough. So make sure, you know what you're doing.

There is nothing wrong at fall in love with some one you really like them. If you are serious about this and want to know the fact that opp. also have same interest, Just do talk with them. And before you propose, first confirm that Opp. really engaged and serious with other person in love. But avoid talks which destroy and disturb their relations.

Before trying to escape or avoid him, talk to him. How would you know he loves you when you never ask...However, if he has a girlfriend and he told you he loves her then it is time to avoid him. Never try to destroy other's relationship. You should have expounded more your discussion so that we could tell you a more detailed advise or point of view. The facts is very vague and I could only make assumptions.... Why can you say that you had fallen in love with the man? Are you dating? How did you meet him?
