Friends or Frenemies?

The situation is I’m getting married. I found the man for me and I am very happy, masha’Allah. Found a great job, as well. Providing for myself, my family, giving zakat, doing all of that. I’ve also bought them treats not for any reason, just because I’m giving like that and with my first pay check from my new job, I bought my close friends and family a little something. They were SO happy! And I was happy seeing them happy. Anyways, apart from that, they can’t seem to be happy for me because of my past relationship which was years ago. At least, that is what I am left to assume because that is the ONLY thing they bring up whenever I sit down to talk them about how I’m feeling about this. Just think about it for a second? Would you always want to be pulled back to your past when you have moved on from it? Would you keep wanting to deal with something that has been over and done with a long time ago? Past is called a past for a reason. I’m heading towards my future now. Going to begin a new chapter in my life. I just can’t seem to understand what’s going on because no other reason but the past is given to me and I don’t believe it’s a valid reason. Am I wrong? Please do tell me.
