8. The buddy circle
You can make a quick conclusion about the person by investigating the circle of his direct and indirect contacts. If your boyfriend invites his friends to your party, pay attention to the way his friends behave and treat him and you. This is a good way to find out many interesting and secret things about your lover.
I recommend you to differentiate his friends. You might meet friends you’d better stay away from, and you might meet really nice guys you can address to if you need some help with you boyfriend. Find out their interests, hobbies and try to communicate with them more often. You can learn a lot of interesting things you had no idea of. Also pay attention to the way his friends treat other girls in the company. It’s perfect if some of them have more or less long-lasting relationship.
Remember that ‘birds of a feather flock together.’ Thus, most probably his friends are the same. Any changes in his behavior also mean he’s dishonest. Anyway, do not let him mock at you or slight in the company of his closest friends. Try to stand the situation with dignity and honor. But afterwards tell him where to go and forget about this guy!
