<human>: Been in a 3ish yr relationship. Great girl, we get along great. Long term life goals - we don't agree (kids, location...etc). She has known for a while that I want to move across the country and now it's happening 5 months from now (with the expectation that we'll have to break up). Don't know if I should wait until after her and I go on vacation or just tell her asap. Vacations is 2 weeks away for 1 week. I feel like I should wait but I also think she will be mad that I strategically waited (withheld information from her).
She won't be too surprised but will for sure be super emotional.

Can you provide a brief rundown of the text in within 3 sentences?
