I texted my boyfriend and said I missed him. He just replied faintly, Oh, aren't you busy recently? It will be fine after this period. I was very sad after receiving it.

I understand how you feel, and feel lost and sad about your boyfriend's cold response. However, sometimes people have different emotions and concerns at different times, especially when they are busy, they may not be able to give the desired attention and response. In this case, I suggest you try to calm down first, and don't be too emotional or make radical decisions.

You can try to communicate frankly with your boyfriend, tell him how you feel, and let him know that his response makes you feel sad and not valued. At the same time, you can also try to understand his busy state and give him some time and space to deal with his own affairs. If you think it is necessary, you can also put forward some solutions, such as making up for the lack of communication by telephone or other means.

Most importantly, maintaining good communication and mutual understanding is the basis of establishing a healthy relationship. Through frank communication, you can better understand each other's needs and concerns and find better ways to deal with this situation.
