<human>: My girlfriend and I have been in a healthy relationship for 4 months. But there is one thing that I hate in my relationship with her (since the beginning) and that is going out to bars/nightclubs together. We might be having a great time but it makes me extremely uncomfortable/jealous once a guy starts talking to her. The problem is not that I'm not confident enough. I know that she loves me, that she loves being with me and that I make her happy. The problem is that I just don't like the thought of another guy hitting on my girlfriend. She would never do something, but I know that by the moment a guy approaches my gf, he just wants to take her home. In some sense I feel like protecting her.

There hasn't been a situation where I have expressed my jealousy to her, except that one time when I was drunk and told a dude to fuck off.

I don't want this to ruin our relationship and I want to fight this feeling. What would your advice be?

Can you condense the text into a few key points?
