Money scam?

My husband has been "friended" on Facebook by an African man. (They have been Facebook friends for around 8 years now). My husband and I have been together for 7 and married for 1. We live in Texas.

For years now, my husband and his family have been sending this man (we will call him Jim)  money, sending him food, care packages, paying for ALL of his necessities including schooling.

Fast forward to my husband and I getting married last year, we have been clashing over Jim. Every month when it comes time for us to help Jim, we argue over the same stuff. (My husband and I are the only ones who send Jim money now because my husbands parents got a second house so they cut back on helping him out).

I have always been weary of Jim. I think he is a total scam and is just using my husbands family for money. They have put him through school, but Jim can't get a job. Hmm. Now Jim wants us to give him over a thousand dollars to "start a business". Hmm. Jim always has problems which require us to give him more money. EX - not having food, his laptop got stolen, his laptops hard drive broke, his mom needs medicine, etc... 

I am all for giving, but when I don't know the validity of Jims situation it makes me mad that no one else sees how fake this could all be? We could be getting Catfishes!!! For all we know Jim could be some rich lazy bum behind a computer screen taking money from multiple people like us. Why would Jim want to get a job when he makes a living off the salary he gets from us each month because he knows we will always give him money?!?! It seems like a no brainer to me but my husband whole heartedly believes Jim is real. I don't understand this and I'm tired of it.

My husband says I should try to get to know him so I can see who he is but I don't have any desire. If someone from across the world starts Facebook friending everyone in our town and has thousands of American FB friends... I'm sorry but who knows who else is giving him money on top of us?? What should I do? My husband is sad that I don't want to openly give money to him and even though he doesn't say it I can tell it just breaks his heart. I don't want him to think I am a selfish person. It we literally fight about this every month when Jim needs money again. Am i wrong?? Selfish? UGHH. 😭

EDIT*****

YES! My husband has face timed Jim before. Jim calls my husband. And has sent us packages before (which came from Africa) as a thank you or for a birthday. 

This makes it very convincing that Jim could be real but I am still doubtful.
