If your boyfriend avoid you from socializing friends does that mean it is...

it depends on the situation and understanding between both of you: 1. if he feels unsecure about you and thinks like you or one of his friends can do flirt, and he might loose you 2. he is just trating you as time pass, thats why he doesnt want to tell anybody about you 3. he is very much possessive about you, but in this condition, he is not a better option for you and if it happens so many times, then you have to have a direct discussion with your boyfriend regarding this.

I am lucky that my boyfriend never interfere with my socializing, but rather encouraging me to mingle and allot a time for my friends. He even make sure to meet and enjoy the company of my best friends. But if he is a person who prevent me to socialize then its better to have a heart to heart talk to him regarding this matter. Maybe he has a problem regarding socializing of his past girlfriends. I will never know till i talk to him, and after listening to his reasons then maybe i will try to make compromise. But if his a person who has a close mind and doesn't listen to my opinion, i will tell him to look for another girl who is an introvert and enjoy being alone for i am not like that.

that would be possesive.too much of possesiveness can be suffocating .better to avoid such a boyfriend than to have problems later.

Depends really. Certainly this is one of the common characteristics of abuse / control in relationships. However, some people are naturally introverted and do not enjoy social situations. Preferring instead one-on-one situations or very small social interactions where they can feel comfortable. I think the way to tell the difference is if your partner prevents you from seeing your family and friends rather than simply avoids it himself.
