>But maybe that's just me being paranoid.

You are being paranoid. Just take it easy and think about which kind of holidays would you like to take your imaginary lover to ^_^

We often enjoy creating some drama about our imaginary friends, but if that starts to really make you uncomfortable, then it's time to realize that they are still imaginary, and that you should refocus your relationship in a more positive frame,...

It's pretty much the same as a normal relationship, but much easier to do, since the only real problem is yourself, not the other real person.
