My boyfriend went on a trip with his family, but he didn’t take me with him

Don’t be too sensitive. It’s always a little inconvenient for the whole family to go on a family trip or something, and you’re still the girlfriend. People also need to have their own personal space, so don’t push them too hard. , he will not be able to bear it. If you want to be more open-minded, wouldn't it be more fun for the two of you to travel in the future? At least he didn't tell you, which still shows that he cares about you. Love does not have to be 100% transparent.

I wish you happiness!
