Brain And Heart Conflict

Hi coaches
I’m wondering when i logically know what’s right to do (I think), emotionally I want something different, what should I do?

Specifically, I’m with my partner for about two years now and we love each other really enjoy each other’s company. However we have different life goals (his being having a family soon whereas I still want to further my career like go work overseas etc.) I think we both know it’s probably not going to work out but yet it’s hard for either of us to have this difficult discussion and split.

Now I’m in this indulging emotion of being confused and I’m constantly thinking what to do because I have this conflict of heart and brain. Please help
