After traveling with his boyfriend, he didn't take the initiative as before. What happened?

I think it is very likely that you and your boyfriend are traveling. Your boyfriend wants to do something for you, but you turned him down. After he has this shadow, he will naturally stop being so active to you, but it should be analyzed from your specific situation. If it were my guess, it would be like this. Otherwise, if a man becomes inactive, he will have other reasons unless you refuse him.

Another reason also means that you and your boyfriend are very close during the trip. He can see every detail of your life. After he knows you, he may think that he doesn't like you that much, because you are not what he wants in all aspects, so he thinks that you two are not suitable. The reason why he has never proposed to break up may be that they have been together for too long, and it is not good for them to break up directly, so he is not so active.

The above two reasons are very likely and common to us, but I think another reason may be that he thinks you are not a good woman, which always depends on what you do.

Maybe he heard about your past from someone else's mouth, maybe you were dissolute before, maybe you did something bad before, and when he heard about it, he will gradually crowd you out, so naturally he won't take the initiative to treat you, so you must talk to him yourself and find out the reason.
