Please help!! I'm sooo sick of feeling this heartache pain! And the crazy thing is the man loves me! But he?

I met this guy in October and fell in crazy love/lust with him. Soon I came down to reality...The guy is a hoarder, has schizo-typal, severe ADHD (he can't hold a job) I'm 31, he's 44, and put me through a hellish experience because he did too much cocaine to deal with him having to move...It was insane, I had to take him to a crisis center, talk to his Mom etc... and he lives in a dream land...He is so sweet to me though, love me undyingly...He is just such a sad case! I am a successful attractive girl and my friends all think I'm so nuts and basically made me feel so embarrassed to be with him I had to leave him! He's not even allowed in my house because my roomates feel uncomfortable and think he's creepy. He comes off to most people as a spun out on drugs, homeless person! But I think he's cute! He's really not bad looking! Did I mention he's a hoarder too? But he is soooo romantic and actually really intelligent, writes me these long romantic messages, makes me feel as if we're soulmates...I am trying to get over him and finally blocked his number after seeing him yesterday for the first time in 3 weeks...He didn't look very good...I want to help him and care for him but I know I'd have to do it forever because he just can't make it well in the real world...Its so sad to leave him to be alone! Please give me advice! Plus I met this other fantastic guy who, of course I don't like, but I would be STUPID not to date...My friends all like him...I now do not even trust my own judgement and feel I should just listen to them now- all the time...But is this right? Will I regret leaving him? I do feel happy when I'm near him, I feel this warm sweet affection- love??? But there are soooo many problems, HELP!!!
