Your question sounds like you're still emotionally a teenager if you are expending energy obsessing over whether "someone you like tried to talk to someone else." The right answer for an adult in this situation is to do nothing. If someone you like isn't behaving as if he/she is interested in you, then he probably doesn't, and you should get on with life. Plus, dating people at work is a risky move. The chances of it working out are very slim, and when it does fall through, what're you going to do then? Avoid them at work? Get another job? Is it really worth it?
You should not date someone when they are with someone else because that means that the person you are with is cheating.
If the other person strongly dislikes the person, then they should get over it and find someone else.
When that someone said they did not like someone else you should have asked why they didn't like that person. It is called 'communicating.' If you like the person the other person does not like don't be afraid to say so.
break up with them
Really a person should be happy with who they are not try to match themself with someone else.
It often happens that we can't choose who we fall in love with. If they like someone else there is nothing you can do. Have you asked this person to be with you? If it is the case that you can't be with this person try to move on, there are plenty of people to choose from, don't give this person the power to hurt you.
If you are involved with a person you catch flirting with someone else, you can confront them about it.
It shows how a person explains the behavior of someone else.
Only if you do not have a boyfriend at the time of kissing someone else.
Such a person is a bully.
Lie to the person you love and say the other person has done something horrid. Then the person you love might break up with them and be your girl/boy freind instead to thank you for telling them.
A bewrayer is a person who betrays someone else, or who divulges information to someone else.
