yeah very familiar with the NEED TO GET OUT voice, for me its always a sign that I am structuring a relationship in a way that is just not going to be sustainable for me long term. Personally I have a lot of trouble with the intensity level of romantic-ish relationships (e.g. expectation that you are in contact most everyday, see each other very frequently, etc) and find I am much happier if a relationship is structured more like a friendship (e.g. you see/talk to each other often, but if you fall out of touch for a few weeks because you are both busy thats fine). I also feel much less pressure to perform a romantic role I am unsuited for if the relationship is non-exclusive (but I am poly, so might not be applicable to you).
