I'm very new to this forum, but the question you posed is one that I have thought about maybe a million times. I have been the one giving the support and being understanding, and what happens when I'm the one who needs it? Further, I sometimes feel that the consistent having to be understanding leads to frustration at always having to play that role, which can stretch my patience thinner and makes it more difficult to be understanding.

I don't have a solution. But it's nice to know that other people think about this and I'm not selfish for wondering how things will be when something happens in my life and I need support from my partner. I am very fortunate to have several good friends who I feel would definitely be there for me if I need them, but I wonder if I'll be able to receive that support from the one who I've consistently given it to.
