Before reading the bulk of text; we didn't break up. We're just currently on a break.
For starters, we've been together for 4 years. We moved to another state together not too long ago too. We've both been struggling with mental health, so she suggested a break to "do our own thing" and "take care of our own problems" before we work on our relationship.
For a little bit more context, our relationship was great until we moved into this new house. At least I thought it was. Over time we drifted apart a little. We didn't do much together, we stopped hanging out really, didn't cuddle and barely kissed anymore. A conversation about it turned into the break. Some of it I will gladly take the blame for. Working 12hr rotating shifts drained me, so we didn't do much together prior to it.
Since then, it's been basically nothing. She's on the phone with one of her friends 24/7 and we barely talk 1 on 1 because of it. She'll even go to sleep with this person on call, or immediately call them back as soon as she wakes up. I rarely ever get to talk to her, last time I had a conversation with her about how I felt she assumed we were done talking and immediately called her friend. The times I try talking to her she doesn't really seem interested. Every time I bring up how it feels she doesn't seem to care. She constantly simplifies her answers to "do what makes you happy." and nothing else.
We finally are going out and doing something together after months of basically not doing much. She told me a while ago this wasn't a date because she didn't want to get confused or anything. She then reiterated and said this was a "friend" date and not to expect anything because she didn't want to get confused because we're technically on a break. I already told her before I understood and have been very careful with her boundaries because I'm respectful of them. I just thought it was unnecessary and it really hurt my feelings.
She's been thinking about taking a job in another state again. I don't know if I go with her or not because if it's going to be like this, except I'm starting over completely with no friends and hoping she speaks to me for more than an hour.
Maybe I'm thinking too much into it. Maybe I'm overreacting. I don't talk to people about my relationship or my problems and it's unfortunately something I've taken upon myself and myself only to deal with. I just don't know what to do anymore. I've been fighting with whether or not to break up with her and move back home, because I'm not sure how much more of this I can take. Any advice would be great. If any of this is my fault, please be brutally honest with me.
tldr; Girlfriend and I went on a break. Since then, she's basically been a ghost. I need advice on what I'm supposed to do now, or if I do anything at all.
