My boyfriend sent me a blessing message before my birthday. What do you mean he didn't call me back after I came back? What mentality did he send it to me?

It is difficult to determine his mentality and intention, because it depends on his personal thoughts and actions. However, the following are some possible situations and explanations:

1. He may have just sent you a blessing message out of courtesy, that's all.

He may still have some feelings for you, so he sent you a blessing message, but he may have put it down, so he didn't reply to you.

He may want to start your relationship again, but he is not sure how you feel, so he didn't reply to you.

If you want to know his mentality and intentions, the best way is to ask him directly. If you don't want to contact him, you can also give up thinking about his mentality and intentions, because this may have no effect on your relationship.
