Yep, I agree with what everyone has said so far!
I think your boyfriend just doesn't realize that being in a sorority is not about parties and things like what it is made out to be in most movies.
Instead it is a deep bond with other women that lasts forever
You do philanthropies, fundraising and things like that.
I think in the case of my friend who opted out of the sorority, her boyfriend was EXTREMELY misinformed... he had a stereotypical view on fraternities she would be going to mixers with, etc. and that is why he was so strongly against it. I really think if she could have made him understand they were not really like that, he probably would not have been so against it.
Follow your heart!
I have to say, I somewhat agree with what Sigmagrrl said "The right boyfriend wouldn't make you feel like you have to choose."
Kind of true to a point.. but at the same time, he might just be worried about you. Maybe scared he won't be able to spend as much time with you?
When my boyfriend decided to join his GLO, I was honestly somewhat upset about it. I knew it was a great thing for him & everything, but it kinda bothered me that we couldn't spend as much time together. (The time we had together was really sparse to begin with mainly because of school & work). Our time together was really my main concern, but we worked it out
So that might be another one of your boyfriend's worries.
