Anyone can be complex if one doesn't expend the energy to understand them. But I know that some people can also be unreasonable and change the relationship rules in midstream. That's not complex - that's mean.
I'm pretty easy to understand. Be nice to me, and you'll get double your investment back.
If you're interested in understanding me then learn what I like and what I like to do and when I like to do it. Simple as that. If you think I'm sending mixed signals then let's talk about it. Don't accuse me of it. Accuse me of anything and I will shut down on you faster than your penis in a swimming pool in winter. But talk to me about it, and we'll have a nice discussion.
And if I'm not understanding what you're trying to say don't get flustered. And please don't keep saying the same thing over and over thinking I'll finally get it because it's probably not going to happen. I'm simple, remember?
Sometimes you just have to cut your losses and move on. Not saying that's the end of the relationship, but there's always a point where we have to agree to disagree.
