<human>: Can you give me a shortened version of the text?

My GF and I have been living together for almost a year now. I'm happy, and until a few hours ago I had no reason to believe she wasn't happy as well. We've always encouraged having an open dialogue, and lately she hasn't let me know of anything about our relationship that needs fixing.

Now, some of my biggest insecurities have always been that I don't have a ton of friends, and that I don't take a lot of initiatives. That I'm "boring" and "safe". Bit of an introvert, really.

I do enjoy going out for drinks every now and then, and I never say no to any social event if I can help it. But nearly my entire social circle were friends with my GF before we even met. I had very little "new" to offer her in that regard.

On to my reading her diary. Yes, I know it was wrong, but what's done is done. I was skimming the last few pages looking for my name, and when I saw it, my heart sank.

This is how it read: "Feeling so distanced from OP right now. Lonely, even. I'm in love with him, but maybe that's not enough? Maybe we won't make eachother happy? Maybe I should look for someone who helps me step outside my comfort zones more?"

Basically confirming my fears. To retiterate, I've never said "no" to any exciting event with her ever (because I'm so self conscious about being perceived as boring). But I haven't taken a lot of initiatives either.

My question to you is: where do I go from here?

Can I ever get it out of my head that I'm not her first choice? Is her mentioning "*looking for someone else*" (albeit not actively) a dealbreaker?
<bot>: GF has negative feelings towards me that she's not communicating. Is this relationship a disaster waiting to happen, or is it salvageable?
