Relationships are a two-way road and they take effort.

It's funny how people know that you can't have a fire unless you first make a spark. But when they lose the fire in their relationship, they blame it to just being gone. If people want to keep the fire in their relationship, they have to kindle it, keep it going and if it dies down, they have to work to get that spark to start it again.

In your case, you are 18 and still have a lot of learning to do, but if you want to work on the relationship, you need to start generating that spark, not waiting for it. It does sound like it's done in which case you should meet in person and break up.

But again, sparks don't just happen. They come from effort.
