Relationships involve sacrifice, but when is it enough?

[Sandi]

If these things (twitter and going to conventions) mean that much to you, you shouldn't have to give them up. If they are a part of who you are, your boyfriend should be able to accept it's a package deal. He is truly making a sacrifice if he's able to trust you with those things, even if it makes him feel uncomfortable.
To me, it sounds like there isn't a whole lot of trust in your relationship (not meaning to offend you at all). I just find it a tad ridiculous that you two have given up on some good friendships with the opposite sex just because you're dating someone. I could understand if your boyfriend was still besties with his ex, and you requested that they do not hang out because of their history.
My one ex use to hate it when I texted anyone but him. Mainly because I refused to let him go through every text in my phone (At the time, I had a female friend who was struggling through some stuff and it needed to be kept private, but my ex didn't believe me). And because I refused to let him go through my phone, he accused me of cheating on him, he didn't trust me. It was a horrible relationship, he didn't let me hang out with any of my guy friends without making a huge deal about it, and he even made me feel guilty about hanging out with female friends because he felt I wasn't spending enough time with him.
My current boyfriend and I have sat down and talked things through. All the things that make us uncomfortable/worried. He and I both make sacrifices for each other in the sense that we let each other live our lives how we want, and trust one another that nothing will happen that would hurt the other. I know he has a passion for his street/hiphop dance, so I would never dream of taking that away from him, even when it makes me uneasy when he goes to all the classes/sessions and travels to participate in dance-offs.

It sounds like you two need to sit down and talk things out. Express to your boyfriend that these things are important to you, and don't be afraid to put your foot down if he still doesn't want you to attend conventions or have a twitter. With this being said, be prepared to make equal sacrifices, if he wants to do something (within reason), keep an open mind and be prepared to step out of your comfort zone. Sacrifices take more than just giving up something of yourself, it also takes trusting your significant other and being willing to take the risk.
Don't keep each other on a leash. It will wear both of you out and eventually slowly eat away at your relationship. To love, you must trust, it is the foundation of a relationship.
