Me and my girl friend run out of things to say when texting...?

I donno man, I've never ended up dating people for long when there isn't conversation
Just cover all the bases
Music
Travel
TV shows
Food
Anything you or her are interested in basically
You could just start with 'whats the craic?' (What's up? Unless you happen to be northern irish I wouldnt go with 'what's the craic?' :'D) And build from there....no closed questions that can be answered with a yes or no
Hell even ask her stuff about herself (favourites etc) send her quotes you like or recommend shows, movies, books, games
Hopefully this helps :)

It's not about trying to find more topics, it's because you text too often. If you are texting constantly you don't have time to live and experience and have a life so the result is you have nothing to talk about and you wind up boring each other. Unless you are experiencing how can you say i heard the funniest thing today or had the worst lunch ever or saw the best show on tv or I finished reading another chapter in my book.

The answer is set a schedule. Texting at lunch and between 8:00-9:00 at night or only Mon., Wed., and Fri. nights for instance.

You have lots to talk about if you experience lots of life.

If you don't like video games, don't read this. Try playing a video game with your girlfriend so you will have lots to discuss about it, that's what I usually do with my friends
