Is it normal to still have feelings?

A month is nothing when you're heartbroken over someone. It can take months, sometimes years, to heal fully. But it's important to remember that it probably didn't work for a reason, you're incompatible even if you don't want to see that. That only means that someone better is out there.

Do something productive to distract yourself. If you continue to have problems you might want to see a therapist for a few sessions, and read some books about getting over breakups, but don't try to get back with this person, because an ex is an ex for a reason.

Sounds like you're missing a partner who broke up with you.

A month is a very short time. Some people grieve for years.

All you can do is grieve for what is lost. And no matter what, you will continue to think about this person and miss them. It sucks. But you two aren't together anymore for a reason.

You miss them because you think something is lost. But is it? It's possible you could meet someone now who is better for you in every way!
It'll be a right.

Just live your life. All you can do
