Sorry I've been out as of late, getting to work on this mixer is time consuming...
Hm... well here's the thing about this... you have been fairly convinced that 1.) you two will get back together, proper and 2.) you need each other. You have also established that you need distance and time apart in order to essentially come full circle. This precludes a physical relationship in the traditional sense. You have previously established boundaries. I guess my point is that being physical may in fact not be the best thing right now, and so the "benefits" to your relationship should be entirely spiritual/emotional. You are there for her, as her anchor, and you knowing she needs that, is your anchor. Now I will admit, for many men (myself included) that's just not enough, but for you it seemed more than enough, you were frankly worried about losing her, and when you didn't you were relieved. So... this could be you, discovering that in fact, there DOES need to be more, and that you're ... patience is wearing thin. I don't know, though... it's hard to say, you're a fairly unique individual and you've expressed differences from the typical male role that defy lots of assumptions in these regards. I'd stick to what you know. If you even question your love for her, you need to step even further back, or risk hurting her, or yourself.
How to talk about it, well... I'm a sucker for Honesty, actually. I also always wear my emotions on my sleeve so-to-speak, which is a no no in many people's book. If it were me, I'd come right out and say it "Dee, yo... we're doing all this, but why? We're separate now, and just teasing ourselves, it's not right..." but that may be too blunt, or even inaccurate. But you definitely will want to say something if this continues to bother you, or else you ARE wasting your time, and investments of emotion, which aren't easy or abundant.
