<human>: My SO and I have been together 2.5 years, most of it being long distance. I moved 2 hours away for graduate school 2 years ago, and we've been doing well for the most part. 

Things have gotten worse though since July, after she graduated and started a new job. Now she feels too tired in the evenings to talk and its putting a huge strain on our relationship. We saw each other for the first time today in 3 weeks, and it felt distant, like catching up with an old friend, not talking to your SO. 

We talked about our issues and its come down to trying to work things out (but we don't know how) and breaking up (or taking a break...). I have 2 years of school left, and she thinks we'll be able to make things work once we can be in the same place. 

I don't think taking a break for 2 years is at all reasonable, but I don't know how to fix our communication issues. Its all made more complicated because she says she wants to marry me and have a family in the future (and I agree). 

Any insight or thoughts on how to handle this?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: SO of 2.5 yrs wants to go on a break for 2 yrs, then try and resume where we left off. I want to fix the long distance relationship, but I don't know how.
