I will try to make this sounds as not cheesy as possible.
Someone who can bear with your weirdness is well…weirder than you. Someone who can stand your jumpy self in the presence of beautiful images of wildlife and cute babies is awesome. Someone who can be with someone else who has the same Enneagram type with his partner is (supposedly) a star. Someone who can stand your never-ending-mood-swings is…pretty much impossible, but, well if someone managed to do so, you should probably bow to him and congratulate him. Someone who is willing to walk 3 kilometers with you amidst a cold winter day is lovely. Someone who is willing to listen to you more than you listen to him needs to force you to listen to him more. Someone who is enthusiastic to museum as much as you do is one-of-a-kind so you should give him more attention. Someone who appreciates your cooking when it is somehow unappealing is heartwarming. And someone who has spent (nearly) two months together with you (since you are not sure the term mensiversary exists) is masih kroco and should really look forward to some second or twentieth or two-hundredth or bimillenial anniversary in the future.
