What does it mean when a MAN is clingy?

Talk to the friend that set you up and try to find out more about his past relationships. Did the relationships end because he was too clingy? Who ended the relationship? Past behaviors will give you some insight on how he'll be in this relationship. For now, go with your instincts. If you feel like you're being smothered, tell him you want some space. Declaring your love and talking about marriage after knowing each other for only one month is scary. Good luck.
