Boyfriend, we have a problem, and then he makes the space between us visible only to himself. Why?

Your boyfriend has a problem with you, so he closed the space. When you two are in love together, a little conflict is inevitable. Couples are like tongues that don't touch cheeks. You two should communicate with each other when you have conflicts, so as to avoid small things hurting your harmony. If you think whose fault it is, who should admit the mistake and apologize to the other party. If it is a matter of principle, you should all settle down and do it.
