DP is 20 years my senior.
Wakey is right - being with an older person is in no way settling. Aside from being older, DP is also incredibly intelligent, funny, interesting, charismatic, kind and supportive. He's also bloody fit.
I would, however, be settling if I set all that aside to be with somebody who I didn't love, but who was in the right age bracket. And I defy anyone to tell us how we should live, or that our relationship is unequal. Actually, it is: I'm the loud, overbearing one.
At some point, yes, I may have to care for him. Such is life - my grandfather is 15 years older than my grandmother and has to care for her - it can't be predicted.
