Nope... not delusional, just tied into something called the "Drama Triangle" (from a guy called Karpman). Google this, and then it's positive counterpart, the "Winners Triangle" (Choy). This might help you get a better perspective on what's happening and how to change your way of looking at, and responding to, your situation.
You also recognise that you place your "value" in what others think of you, which seems to revolve around being seen to be supportive. However this raises the difficulty that you are being supportive, not to support him, but to create an impression with others. This will inevitably limit your ability to act in the best interests of your partner and yourself because you're always trying to second guess what "others" will think of you. This means you'll have difficulty weighing up your choices appropriately, because the fear of "what others think" presses heavily on one side of the scale.
This internalisation of "others" is often the result of upbringing....trying to stay safe in a chaotic world where vigilance to the moods of others was required to stay out of danger.
