Basically my GF ( of 3 months) knows I've slept with quite a few women and has from time to time got a little pissed off about it and called me out on it, now I rightly or wrongly I told the truth and explained to her how I just couldn't find the right relationship and a decent girl. She obviously is teasing most of the time and I joke back and laugh about it myself.

So today I talk about moving areas and she txts saying something along the lines of "you ran out of girls to sleep with so your moving on to fresh ground (wink)", I joke back saying "yeah they weren't my type around here" and she replies "Im sure you can find some sexy girls in your new area". It's all joking but I can't work out if the undertones are she's jealous/insecure or that she's happy for me to sniff around and push me away. In a way it pisses me off as she still thinks i'll stray, though I've reassured her before. I understand as she was cheated on previously BUT its annoying feeling like its a big joke and I can't work out if she's serious or not.

What kind of responses should I be using if this shit comes up in conversation or text again?

thanks.
