ah, there's a difference between being altruistic and a schmuck. There's also a difference between being in a relationship (give and take goes both ways) and doing something for others without thought of a return. I think what you're talking about is being in a relationship and feeling that you're kindness is being taken for granted. That goes back to the nice guys finishing last concept (they don't always but it seems like that sometimes).
Quote:This sometimes make me expect certain things from her. I expect her to be there always when I need her and stuff. But, when that doesn't happen, I am pissed off.
So, is there some kind of score card you're keeping? Like, I've done a, b, and c and now I'm looking for x, y, or z? Expecting someone to always be there when you need them is not likely to happen. The always part is your issue. People are individuals within and outside the relationship. They have there own stuff going on. No one is always available and you have to decide if the times that she isn't available for you are excessive to what you can stand in a two-way relationship. Is she Ever there for you? Sometimes? Most often? Look at your expectations of others (payback, always available) and ask yourself if they are reasonable.
On the giving side -- does she appreciate the energies you give to helping her? Does she enjoy your company or do you feel used? You may decide that this particular relationship isn't working for you or you may decide to take a more altruistic approach and not think in terms of what you get back from giving.
