UPDATE
Didn't particularly want to relive this thread, but some updates...
Going to fast forward a bit, but somehow she's in love with me again and wants me to move in with her even tho we haven't visited since things really went downhill. She's getting her own place in a month or less. We've been doing a lot of talking and she says she really doesn't care if I had my own place (I would still spend most of my time with her), but financially it would be way better if we lived together. This all looks and sounds great when I type it because I am genuinely in love her also, but I'm scared about a lot of things.
The overall thing is this would be huge life changing decision. As sad as it sounds I've always lived at home (although I pay rent now), and have lived where I am currently for at least 16 years. The other thing is I'm an alcoholic and this is what really almost destroyed our relationship. But at the same time it's what I turn to in times of stress and anxiety. If I do end up moving in with her I don't want to make the same mistakes I've made in the past, but really haven't found any other coping mechanisms successful. And for sure moving their would be a huge cause of stress and anxiety for me. Also since she's known me she knows that I'm not a kid person. When I first knew her she was in a different mindset and wanted her kids to be with her ex. Since then that's changed which is good but it means that I would have to get used to being around her kids sometimes if I did live with her. And it's not that I don't like them but at least for younger kids, it's like sensory overload for me. I just don't know how I would handle it.
Other than that, I hate living where I do now not so much because of the physical location, but whom I'm living with. But at the same time I've become kind of complacent because I don't have to worry about a lot of the things I would have to worry about if I was living with someone else or on my own. I guess you could say it's kind of a false security. Anyways, if anyone's bothered to read all of that I'd greatly appreciate any advice. Even tho things are going good with her, I feel like I'm kind of on the verge of an existential crisis. Do I just bite the bullet, move in with her, and hope everything somehow turns out?
