My boyfriend never returns my messages. There has been less and less contact recently. What happened?

In two cases, you should contact your own situation and think about which one is more in line with:

Maybe he's been under a lot of pressure and busy with work recently. There is very little free time, so I can't spare time to accompany you;

Maybe he thinks you are bored, wants to run away from you, or has a new feeling for other girls, which is a sign of playboy;

In the first case, you should give him his own space and let him rest.

If it is the second case, never tolerate it, otherwise, it is yourself who is injured.
