It is not really difficult to tell if the guy is interested in you. Most of men would do the following:

1. You keep receiving his text
Your man might be texting you all the time. This is because he wants you to remind you about himself. He keeps thinking about you too. Respond to his messages if you are also attracted to him. If it does not disturb you and makes you feel special, let him know that you appreciate his attention. As a rule, men dislike texting, but if your boyfriend enjoys being in constant contact with you, it merely means that he finds you amazingly appealing and unique. You are lucky that your man’s world spins around you. Maintain that relationship.

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.
