We officially broke up about three weeks ago. Together for nearly two years. She broke up with me, I didn't fight it and agreed it was best as I was unhappy too.

She wanted to be 'friends' I said, we'll see how it goes. When we exchanged our belongings after going no contact for two and a half months prior to the 'official breakup', she was wary of me, but I was very cool with things and we ended up catching up on one another's lives etc. Ended up having a nice friendly evening. No sex but we cuddled when I left as we were still 'over'.

A few days later she starts writing and liking posts on my facebook and texting pretty much everyday which started out slow at first.

I'm not hundred percent sure I want her back, but if I do, there's so much that needs to be worked on, I will not go back to how things were.

The texts are very random and have nothing to do with our relationship, they're everyday things. Friend speak, if you will.
The banter is back and we're constantly negging and calling each other names which we hadn't done for months!! She instigated this.

I don't know if she wants me back, but it's usually her sending the first texts. Although she's getting control as it's normally me who ends up sending the last text of the day! There's no clue to when she will stop texting for the day, even if I've sent a question, she may not respond to that, to ensure it looks like I care more.

We're meeting up for a drink in the week, which will be the second time we've actually seen on another in person in over three months! God knows how that'll go.

I'm wondering if there's anything I can say or do in text to get more of an upper hand? Other than taking ages to reply or not.
I'm wondering if calling her mate, or calling her my illustrious/esteemed friend etc to neg her but make it more obvious I regard her as a friend as reverse psychology?

Any tips? Thanks.

In 99% of cases, there's no such thing as going back to "just friends" after a breakup. It just doesn't work. There's always either some form of subtle hostility, or sexual tension (one extreme to the next, I know). It seems like it's the latter for you, which is good if you want her back.

The nice thing about getting back with an ex is that it doesn't require you to put on some facade to try to win her over. She already knows everything about you and she clearly still likes you. And in this particular scenario, it's clear that she wants you back. The #1 sign that an ex wants you back is when she contacts you randomly and talks about stupid shit.

It's also obvious that you want her back too, even if you say you don't unless "things change". Otherwise you wouldn't have made this post. With that in mind, just make sure you're careful you don't get hurt by setting your expectations too high. Things ended for a reason and she's definitely not obligated to change her ways to accommodate you. In fact, most girls don't change even if they say they will. That's a risk you'll have to take if you want to try again with her.

Thanks mate, I think you're right with the latter.
I ushered her to approach me with a cuddle and she did, then I pretended to rub my nose on hers, but I did it so slow she thought I was going to kiss her, so I did.

I think because she thought I was going to be cold and perhaps a bit off with her, I confused her by being very much in control and led the evening. I was very reserved and too comfortable when we were in a relationship, so she perhaps saw me as a challenge that evening especially since I was making no overtures to get her back which I think she was hoping for or least expected!

It's kinda ironic that she broke up with me, I had my faults sure, but it was her that was sabotaging it and pushing me.
I think she knows she was doing that and then breaking up with me because I wasn't reassuring her with my affections, she shit a brick now she's broken up with me and I'm 'okay with it'.
