I don't know how to quote...sorry.
In response to you Eve, the battle between needs vs wants is a difficult one, I agree. I don't believe that needs will win. Not if you are committed to the relationship and working on it with your partner. As a supporter, I have needs, which are not being met, and it's been a while, and it would be so easy to just be with a stranger to get those needs met (and I have the means, and mode to do that), but I am committed to my partner and working on it with him, I would expect him to do the same (and he is). The relationship is worth more than mine or his needs being met right now. It is hard but worth it, if you truly love someone, you will be willing to work on how you can meet each others needs and not take the easy way out to get some need met right now. Human connection is a need, agreed. Human connection doesn't always mean being in an intimate relationship with someone. If your need is an intimate relationship then be willing to work on it, when things get real, instead of being with a stranger to get your needs met.
In response to lostforgottensoul - I don't think anyone plans on leaving when they start a relationship, but if it keeps on happening because it's easier to be with a stranger, then there comes a point where you should actively decide to either not start those kinds of relationships or be willing to work through it with them to continue being in that relationship no matter how hard it gets.
