It's hard to have a simple relationship with some people. You have problems with them like:

• arguments
• jealousy
• suspicion

To describe a relationship like this, you can say "there's always drama with (someone)". That's because these are the kinds of problems that characters in plays and TV shows have.

You can say "there's always drama with ___" about a single person who causes problems, or about a group of people who always have problems with each other:

There's always drama with you.

Jeez! There's always drama with these guys.
