Ill fiance, doubt and loyalty matters

I got engaged 2 years ago. we only knew each other for a short time, and all seemed magical. when we met, he had just lost his job due to mental illness, but he was in therapy, so I believed it was just a temporary "bump". I have a very demanding career. over the past two years I had to move between 3 different countries. he was always as supportive as one can be, and followed me. but he failed to find any occupation for himself. the frustration of living with an unemployed, bored, lonely and depressed man got the best of me. I no longer felt attracted to him, and at some point even declared a breakup, saying I don't want to spend the rest of my life with a man who can't even take care of himself, let alone a family. so in country nr.3, after a few more months of endless fighting over his lack of motivation (and consequently lack of money and general stress), he went back to his parents, who are in a different continent... and then he visited another psychiatrist, who believes my fiance was wrongly diagnosed. according to the new dr., his mental illness is different and more severe. and he is not likely to cope well in a "hostile" environment,like a foreign country. so after all this mess, I find myself engaged to a man, who is more loyal than a dog, loving, and willing to do anything for me, but is actually not really able to do anything, stuck in another continent, and got me drifted away already. despite numerous claims by friends (and some mild ones by family) saying I deserve better, I was holding on to the idea that honest, loving and truly kind men are hard to find, so I would not be letting go of this one. and time and time again convinced myself he just needs to put himself together and all will be great. but now there is this other guy. I don't really think there is anything "better" about him, compared to my fiance. But I am very attracted to him. so now it breached the wall, making me wonder if this whole engagement is not an idialization, relying only on what I wish for, but not on what is really there. I am very much afraid of leaving my fiance. he is a really great person, not one I am ever likely to meet again. we share similar values and dreams. but I begin to doubt I can handle a schizophrenic, to wonder what would I do if he doesn't get better, when would I give up (because I do not agree to spend my whole life taking care of a crazy man), as I have been stretching the line a lot all along. and am I missing on some great things while waiting in vain for him to come around? I don't even know how to begin putting my mind in some order...

In my opinion, if you are not truly honestly happy at face value of the relationship.. why are you in it? He may be a great guy.. but if his constant depression is.bringing you down.. that's not good.. at all.. I understand you care a lot for this man, but you need to do what will make you happy now and later.. you need to find the place where your heart and mind have a mutual agreement. Not one overpowering the other

It sounds like you are a very smart woman and knows what she wants in a marriage. Although it doesn't sound like you will be happy with your fiance if you are already having feeling for another man. If marriage means a lifelong commitment to you, I suggest you hold off on marrying this unemployed, boring depressed man. Who in their right mind would want to live a life with someone like that? I think you deserve better. Although I feel bad for him, and hope he gets the help he needs, but no reason you should ruin the rest of your life taking care of him. GOOD LUCK, I believe you deserve better.
