I think that he actually didn't lose his feelings for you but he seemed to be just...very confused and insecure. Problems with work, money and car... seems like those problems buried down the feelings that he had for you or he just buried down the feelings purposely because he felt lack of care from you. It's hard to think clearly when you see problems here and there...especially when it seems like the problems won't end.

I might be wrong, but it seems like you didn't show him your care enough. I think this is the one thing what made him even worse and more insecure.
Think about it... were you there when he needed you? Because it seems like you weren't. But showing your care, being supportive... that's what he all needed from you. That's what he needed to gain some hope. I'm sorry to say but this is what I read from your post.. lack of interest and fear of showing your feelings.

„I took it well and showed him that I was fine“
How fine did you show yourself to be? You weren't fine, right? Girl.. don't hide yourself behind the mask, just be...genuine and true for yourself...and for others...

Anyway, I feel sorry for you and I feel sorry for him. I think that you should talk to him, just to ask how he is doing..

Take care!
