I have recently begun dating someone and I am worried about his upcoming trip with some friends. I can’t go with them because I don’t have official leave, but I know there are going to be some female friends of his whom he has known for years. I don’t know anything about the kind of friendship they share, and I am aware of how insecure I sound by being worried, but I don’t know how to manage this feeling. I have been panicking because I don’t know if I can trust him and if he will change his mind about us. How do I control these feelings?
Relationships take time to get stronger, and trust is one of the critical components that defines whether something will last. It’s okay to feel insecure but it’s also important to temper this with an acknowledgement that you don’t control your partner. As you have pointed out, you don’t know what kind of friendships he has with the people accompanying him. What you do know is that you have both decided to give this relationship a try, which is what matters. Without trust, there is no future for either of you. He is on a trip, but he will be back too, and you can use this time away to work on how you both communicate. Separation will always be inevitable at some point, so recognise that and concentrate on what you are trying to build instead of assuming this won’t work. It isn’t easy, but you can’t build a strong bond without faith in the person you’re with.

I’m in love with someone who almost never replies to my messages. Does this mean she isn’t interested?
Why think about the worst possible scenario? If you have questions, ask them, because a direct response will prevent you from jumping to conclusions. An inability to communicate doesn’t imply anything, but a clear response will make it easier for you to know where things stand and move on if there is no hope here.
