My (29F) sister (28F) is really mean to my husband (29M).

Our family was going on a vacation, and my sister said she needed money to pay for her airfare, etc. She lives in a different state than my parents and I do. I agreed to give her the money under the condition that she pays it back. I sent her the cash and she didn't respond. After a couple of days, I texted her to confirm she's coming on the vacation. She didn't respond immediately, but my parents said that she definitely is. We had more back and forth, but ultimately my sister said she was unable to come, because she was on a bad budget, but still promised to pay me what she is owed. I told her she doesn't owe me now and just reschedule the trip. She said she needs to be with her partner because he is sick. We were not able to reschedule the trip so I just said okay. She still did not pay me back though.<br><br><br>My husband heard about this and he was unhappy with the situation. He insisted I get my money back. He texted my sister and said it was not okay that she didn't pay. My sister then told me that my husband had a big attitude with her and that he was very mean to her. She then said she wants nothing to do with him and that she doesn't like him. I apologized and said she doesn't have to have a relationship with him, but they have been in contact ever since we were children. My husband insisted my sister was lying and that she was trying to make him look bad so she could keep the money. I showed him her texts to me and he denied their validity. He then texted her again and said she was a liar and that she had no conscience. He said he felt bad for me being related to her. I apologized to her again and she said I needed to stop apologizing for what he did. I said she owed me money so she had no right to be mad. She denied she ever agreed to pay me back, but told me she was going to pay me back before my husband stepped in. She said my husband ruined her trust in me. I told her I wasn't going to give her money anymore. She said she didn't need it now. She said her boyfriend was out of the hospital now. I told her I was sorry to hear that and I wish she was there for the trip and told her I missed her. She complained that I never contact her and that I don't care about her. I said I don't want to be in a confrontation with her, so I stay away from her. I admit now that I should have stood up for myself so we wouldn't be in this situation, but I don't understand why she is blaming me. I don't think my husband had a right to contact her the way he did, but I can see why he feels the way he does. I understand why he just wants me to have my money back. I truly believe she was not going to pay me back if he didn't step in.
