My next D&D Character

My primary creative outlet is playing D&D. For the last 15 odd years I have been running D&D for a group of really good players, keeping these guys busy can sometimes be a part time job. The problem with always being the Game Master is I almost never get to play, however, this gives me years to think about character ideas and interesting builds. Recently I have joined another group as a player and I am now getting to release some of my ideas on the unsuspecting world. My current character is a 4th level Human Variant Wizard, with 1 level of War Domain Cleric (Wizard 4/Cleric 1), this allows me to do all sorts of cool things, like cast spells even if I am wearing armor and have a weapon and shield in may hands.

So now I am thinking about my next character. I have not begun his build yet, but I am thinking about his background. The character I am playing now is really just a proof of concept character, because low AC wizards annoy me. But this next character I want to be a story based character where his background is more important than his class and levels. The grain of my idea starts with Lancelot, a knight who has fallen into disgrace for the love of a woman. I want my character to suffer from unrequited love, but I don't want it to be all emo and depressing, I want the story to be at least a little bit silly. So here is my preliminary background story.

Du Lac (Lancelot's last name and my current working name, it may change) lives in a small forrest kingdom with a large Elven population. He himself is a knight bound to the king of the land, he served his king well and was chosen to become a Paladin.  Du Lac was sent to train among the elves for his eventual ascension to Paladin hood. While there training, he met and fell in love with an elf woman named Eruwaedhiel. She was just as in love with Du Lac as he was with her. However, she being an elf meant she would outlive him by a thousand years, it was was also true, she was already 100 years older than he was.  While the age difference did not matter to him, it did matter to her and the thought of outliving him saddened her. Their relationship was brief, but it left its mark on both of them.

Du Lac and Eruwaedhiel do not avoid each other, in fact they are always in each others orbit, always aware what is happening with the other. Du Lac often goes home to visit her. Their relationship has many strange quirks. Du Lac pretends he cannot pronounce Eruwaedhiel's name and calls her Goddess, Eruwaedhiel knows damn good and well he can pronounce her name and in turn refuses to use his name, simply calling him Paladin. Du Lac endlessly flirts with Eruwaedhiel, which exasperates her, she is often heard saying to him, "I should have just slept with you and you would be over this nonsense by now!", to which he usually replies "If you had just slept with me, we would be married and have three children by now!". While she refuses to allow a romantic relationship, she does recognize his love for her, she knows he will love her until the day he dies, for this she allows him to carry her favor, a small medallion with her family crest hanging on a silver necklace. She tells him when he dies she will give it to another, but they both know that is not true.
