I went out to live with my boyfriend, but there was a kiss and hug. He went to the toilet three times and stayed for half a day each time. What's wrong with him?

There are several possibilities. One is that he doesn't want to touch you, and he's not ready to spend the rest of his life with you. The other is that he may be nervous or have some secrets that you don't know. If you really love each other, you can try to communicate, or you can feel his problems with your heart. Don't be suspicious for no reason.
