When I got with my partner, it was at the same time my sister and her husband were going through a marriage breakdown, my partner liked my sisters husband right at the start, he's a real easy going guy, great to get along with. At that time my sis and her hubby both worked in good jobs, but then they moved and he ended up in a dead end job which he then had an accident in, which caused irreparable damage to him, which inevitably caused the marriage to break down because he wanted to sue a massive corporation which failed, they then broke up. Not long after my sister found another guy and they got engaged to be married. Here's the problem, the new guy is extremely successful in business and not without money, aka rich, and when we went to family gatherings my partner noticed how excited my mum was for her, my partner now calls my sister a golddigger, it's horrible because before that my sister had asked me to do some design work for her for their businesses which of course I did, but then apparently according to my partner I wasn't allowed to be paid. Cut a long story short my sister is getting married to the rich guy and my partner told me he will break up with me if I go to the wedding, like there is no negotiation, if i go then I will not have anywhere to live, and my Mum already told in the past since I got with this guy that if anything goes wrong, to go to a women's homeless shelter, which in my opinion is nasty as she's never been homeless before as she's only ever been looked after by my Father who is an Angel. WTF do I do.
