<human>: So my girlfriend an I have been together for just over a month, and we really like one another, this is actually my first relationship. She as some guy friends, but for I do not really care that she has them, however there is this guy friend she has is a former friend of her ex. So yesterday when we were skyping (we are not long distance) she started saying how that friend (let's call him Mike) wants to meet with her. She even went on saying how she and mike used to visit an abandoned mental hospital and how they smoke hookah together, so basically the way she was talking about him just made me feel that there are some things I cannot do, she basically presented him has this really tough guy who is super brave. I am not the jealous type, and I trust her 100%, but it is more him that I do not trust. And I do not want to seem like a control freak, since with her last relationship, her ex would not allow her to have guy friends, and I do not want to me like that. But at the same time she says how she really likes me. Yesterday when she mentioned him I did not say anything, but I am debating whether I should, but the thing is, is that I have never been in a relationship and I am afraid that I would say the wrong thing.

Can you condense the text into three sentences or less?
