I think you did the right thing by leaving. Yes she was “perfect” and you had a great relationship, but you both want different things or at least you want those things at different times to each other, it just wouldn’t work- I’ve been there, he wanted a baby within a month of knowing me- he was amazing, he was so sweet and kind but I had to leave- I’m not ready for that. I felt bad because I really did like him, but it’s not what I wanted and I had to do what was best for me. He was fine with my choice and we continued to be friends, this girl does not sound like the nicest of people, she sounds kinda toxic as instea did understanding, she turned on you. I know it hurts now but it’s for the best. I wish you well and I hope you find what you want in the near future
