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

you can talk about how you feel about each other and sexually things or what turns each other on or what made you get that person attention in the first place or how you miss her or what you love about her and ask is she ok is there any problems you think i can help with or you just need someone to talk to

Hey do you wanna come over? When am I gunna see you next? Do you think ima good person(lol)? Just think, anything that pops into your head while talking to her or anything that's going on around you.

You could say things about your first date together and that like say remember that remember this..and it would get in to a good conversation.

I would agree that if your girlfriend is the flirting type then experiment and flirt with her through sms or email often. Be creative.

Asking inane questions like "favorite this or that" or "how was lunch at work" etc gets tedious and your girlfriend might find it boring.

My advice is to use your common area of interests and research news about these fields and update her on it, tell her your opinion and ask about hers.

Talking about the distant future is also good topic starter. Where should we go for vacation next summer etc or what would you call our next/first child if we were to have one for example.

Other topics that are good through email are more deep conversations about philosophy, you dont have to be an expert but this can be a fun way to discover how you girlfriends mind operate on a higher level ;)

It really happens when you are always texting each other...try to ask her what happens to her the entire day and let her talk...
