relationship blues

I am very wary of my relationship at the moment...
I love Dario, I do ....but I am so tired of his ways. Certain ways that leave me stuck with either more work, his work, or generally a mess. He is unreliable, can't focus (his ADD is adding an extra notch of stress), and just doesn't care. This is how he keeps his cool, which is ok, and I am happy for him. Unfortunately, he is messing with my cool and I just can't take it anymore.

I am super-edgy lately. Total bitch, if I may say. Especially, considering the fact that he is mostly very nice to me. Nice but unreliable. Nice, but inconsiderate. Nice, but blind to my stress at work (or unable to react to it properly).

I feel like I've been let down on a promise. A promise I was stupid enough to believe. I mean, I have been with the man for 11 years. I should know better.
He promised, he'll take care of everything. He'll master the household, take care of things so I don't have to worry. I told him that my job will be much more demanding and I believed him when he promised support and hard work on his part because I wanted to believe him. I wanted it to be true so badly that I ignored my reason and memory.

I love him and I always want him to be in my life but I am not sure I want to be in this relationship anymore. :(
Why can't I just beam myself to the future? Skip all the break-up drama, resentment and (understandably) resulting hurtfulness from his part and just be good friends, who care about each other and the well-being of their children.

Maybe I just need some space and maybe we just need some time apart sometimes. We have been spending way too much time together lately. Quality time is vital for every relationship but enough is enough. It's always about dosage, as they say... And I've been having wayy to big of a dosis of Dario. ;)
I need him in a different way. Intimately and as my family...but he's been substituting as my hang-out partner lately and that just won't work for me on a long-term basis. We have never had the same sense of humor (in fact, I can't stand his "funny" - always sexually suggestive - comments) and we certainly don't enjoy the same conversational topics.

sigh.
let's see where this is going.
no good phase can last forever, right;)
so, I guess, here goes the bad phase.....again.
hopefully we'll make it....again.
