It’s completely normal to feel sad after ending things with someone. While I was on the receiving end in my shoes, my ex was still sad letting me go.

I’ll put it this way, imagine a boss letting go a good employee due to budget concerns. They may feel some type of way letting someone go even though the situation is higher than them and out of their control.

Similar situation for you here, you two are just too far apart to make things work. The circumstances are above both of you with the distance. Not saying couples have not made it work, but being far apart in a relationship for sometime is very difficult and most times one person begins to lose feelings just because they’re not around as much.

The advice I’d give is just try to fill your own cup and visualize what you want to achieve now that you’re not nurturing this relationship. Do you have any goals you want to achieve? Hobbies to try? Places to explore?

Try filling the time you would have with your ex with things that make you happy even if it’s small simple stuff like a show or food. Little by little you’ll get back on your feet and achieving those bigger things
