Moving In

So my girlfriend and I have tentatively decided to move in together. We've both spoken about it on multiple occasions, but the reality of actually doing the deed is getting to her I think. It's funny as I've been there every single night since we've been dating, but something about it is bothering her and I'm not sure how to handle it. As I scroll through her old photos on Facebook, I feel sad. I don't feel sad for her so much as I do for myself. She has a lot of photos of her and her friends having a good time. During those years, I wasn't having a good time. I was stuck in a process of fixing a dilapidated house that my ex was adamant about getting right so we could continue investing in more properties and become rich. If you've read any of my blog, you know how that ended. So looking back through my now-girlfriend's picture album makes me sad as she's been developing relationships and living her life while I was a hermit who only spent time by myself reading and living vicariously through those stories. I feel I'm a sham. I was socially awkward with her family and friends because my adeptness in those situations isn't fully developed. So now she has it in her mind that I don't like them no matter how much I tell her the opposite is true. I put some of my things in her apartment and her cat is freaking out, so I don't know if she sees that as a sign or what. I feel like I'm some sort of alien life form who can't relate to anybody on this planet, no matter how hard I try. I feel like I'm doing okay, but everything I've been up to for over the past year has been out of my comfort zone. I became a truck driver. I live in half an office with my best friend. I became a welder. I go to the bar on a regular now. I meet new people almost every day. But it's not what I've developed over years as a habit and I'm not used to the social setting. I don't believe there's anything wrong with that, but it's going to take some time to develop and I don't know if my girlfriend is okay with who I am. Maybe I'm just permanently damaged and I'll never be able to relate to anybody. If that's the case, I suspect she'll probably break up with me and I'll be alone for the rest of my life, as I'm unwilling to ever try this relationship dance again after meeting someone as amazing as she is. I guess I'm just damaged goods. This I can be sure of however: I will never force myself upon her or demand something, as that has been done to me in the past and I find it unacceptable in every capacity. I will be a gentleman even if it's to my own harm. And if everything goes south, I'll make due as I am a man and I have a responsibility to do good regardless of the cost to myself. But it's nice to be happy. I haven't been in longer than I can remember.
