Mad at my husband!

Christina
I have to rant! My husband is really a great guy and very generous. He lend a friend money a few years back, when the friend's business was in trouble and actually ended up hiring him after the guy had to close his business. For month now I have been asking my husband how much money he exactly gave him and when he is going to ask him to repay him. He always says that he has to check his paperwork and that he will ask his friend for the money when he figures out the total. I guess it was multiple amounts over some time. He has said that it is around $20,000. I was looking through his phone, I do that sometimes to see what is going on with his family and he knows it and is ok with it. As I look through his emails I saw a message from his friend asking my husband, if he wanted to look at a house with him that his wife and him want to put an offer on. I got really upset because he didn't mention this to me. I knew that they would eventually buy a house and that's why I have asked my husband so many times to ask for the money back. I feel as soon as they buy a house there is going to be no way that they will pay our money back!!! I'm so mad right now and feel that my husband is getting taken advantage off, if they could buy a house why can't they pay their depts first! Now my question: I'm friends with the wife, we actually met in college and introduced our boyfriends. Should I talk to her, since it seems like my husband won't?
