The first one is just like us girls. He likes you, but you don't accept it I don't know, he is proud to let you tell him that you like him, so he will stimulate you in front of you and give you a lot of people to chase. He is very popular. If you like him, just say it. If you like him, you should take the time to accept him.
He likes you, but you only accept his goodness, but you don't agree with him. When he is with you, he can only mention other girls, and then he wants to stimulate you and let you know that he is actually very popular. In fact, he is also liked by many girls, or let you know that you are just an ordinary girl. You can see how good others are, so be pragmatic and accept them.
The second is that he chased you for quite a long time, and you didn't accept or refuse, but he accepted his invitation and gave you a gift. He is nice to you, but he doesn't agree to be his girlfriend. He may feel tired of chasing you. If you don't think he can get along for long, he will think about chasing other girls, but after all, he has been chasing you for a long time, so he just wants to see if he can stimulate you with other girls.
Sometimes boys talk about other girls in front of their favorite girls for some purpose, either to show you that they are actually quite attractive or to tell you that others are so beautiful that it is not so difficult to catch up with you.
In fact, if you don't like this boy, just tell him directly. If you like it, promise to try dating. There is no need to keep putting it off and let others chase you for half a year, which is unbearable for any boy.
