How To Tell If My Girlfriend Likes Another Guy

Feeling secure and trusting are some of the key ingredients of a strong relationship; however, if you're thinking, "I need to know how to tell if my girlfriend likes another guy," you can threaten your relationship by getting into territorial mode. She may say something that annoys you that involves the other guy, and sometimes her actions are hard to miss. If you feel there is competition between you and another man, you can tell whether she really likes him by how your girlfriend is expressing those feelings.

1. Constant giggling or playful hits. Watch how your girlfriend acts around this guy. If she likes the other guy, she will giggle at every joke he makes or hit him harmlessly on the arms. Normally a girlfriend does this with another guy if it is her guy friend or coworker that she feels comfortable around.
2. Saying his name in a conversation. There is nothing wrong with mentioning someone of the opposite sex (even if it is a friend or ex) if you or your girlfriend are discussing something that reminds her of the guy. However, it can get irritating if she says, "Dave does this and that" every single time you two talk. If you often wonder whether she should be talking to Dave instead of you, she might actually like Dave more than you.
3. They have nicknames for each other. You know you’re the only one she has a cute pet name for, other than her dog or cat, but now suddenly you might overhear pet names that she has for another guy she likes. She should know that cute names are reserved for you only, but she seem clueless about that.
4. They're hanging out a lot. The biggest clue that your girlfriend likes another guy is when she hangs out with him a bit too much. They go to the movies, to restaurants, or on a vacation together, alone. When you feel there are two boyfriends in the relationship, and not just you, be cautious.
   

While it is OK for your girlfriend to have guy friends, if she goes beyond certain boundaries, it is a problem. Discuss the issue with her so she knows three is a crowd and has respect for you and the relationship.
