Why does my boyfriend need so many friends (girls)

I have been with a guy almost two years. he says he loves me very much. Yet, we fight all the time. he says im insecure. he has many women calling his cell phone 24/7. he also has many women friends on the internet whom he chats with. He calls the girls friends but many like him and want more. he calls them back when im not around because they are friends? How can I not be insecure when they call all the time and some even offer sex? He says I should not worry because he is with me. he lives with me. He loves me. Why does he need all them?

in case if you break up with him

It sounds to me that you are insecure...but you want to know what you have a right to be. I don't want to stereotype guys but usually if they have female 'friends' that they only talk to when you are not around something is up. Try inviting them over for dinner, or even suggesting ya'll go to a club, or out. If he acts weird or shady then these are more like booty calls then friends. I'm not saying he doesn't love you and these aren't his friends...just becareful and protect your heart. If he is cheating the truth will come out in the end. But if you do love him you must trust him, but there is a difference between trust and being insecure! Only you can determine the status of your relationship with him, but for his benefit don't jump to conclusions but also don't be stupid.
