2. He feels proud of being with you around his friends, family and other people
Public places and seeing each other in a private place where other people do not see you are two different things. If you are dating a man who does not mind being seen with you by his family, friends and other people, it means he is happy to be in a relationship with you. He is very likely to be ready to start a serious relationship with you. Otherwise he wouldn’t be too willing to be seen by other people in public places. This sort of attitude is the right sign telling you how seriously he takes you in his life. You play a very important role in his present and he might be interested in developing this relationship further.
