My boyfriend used to call or send text messages to greet me once or twice a day, but now he doesn’t even send text messages. Why is this? Has he changed his mind?

Not necessarily

1 At the beginning, it felt fresh, but I was afraid that you would run away, so I always called. Now that the novelty is over and the relationship is strong, I don’t take the initiative to contact you anymore. This doesn't mean he has changed his mind! Boys are different from girls. Once they feel that the relationship is established, they will feel that they need to contact each other only if something happens, and there is no need to contact them if nothing happens. They feel that it is an unnecessary waste of time and money, so it is not that they have changed their minds, at least there is one Most boys are like this, and it seems normal to them

2 He has been too busy recently, so exhausted every day that he has no time to contact you (when a boy says he is busy and has no time to contact you, then Not necessarily an excuse)

3 He has been under a lot of pressure and in a bad mood recently. Boys like to be alone when this happens

4 His feelings for you have faded

5 He has found a new love

If you have no other basis, the latter two possibilities are very small
