Hi I’m a 28 year old male and just recently I have had a problem with my girlfriend so whats happening is were really close but her sister hates me and today I was asked by my girlfriend we will call m if I was cheating I wouldn’t ever do that but then I hear That her sister told m that I was cheating so this is what I did to retaliate now I have came in to money and m’s sister asked for some because “ your dating my sister I’m basically your family and family helps Eachother” now I do agree with that but she wanted a all out 35,000 dollar vacation for her husband and their family if they were in real financial trouble I would help but that’s a vacation oh and SHES HATED ME FROM THE START.So m wants to break up because she trusts her sister more than me what should I do?
