Fallin in love.?

Yes I think you may be falling in love with him or the idea of him anyway. He sounds like he may have some relationship issues. He has few friends and depends on you for a lot in the friendship area. How is his relationship with his family, this is important? If he is pressuring you to make a commitment so soon then he may be an abuser. It would be a good idea to see why his last relationship failed, the story he has told you may not be entirely true. If everything is above board go for it.
