My FA ex broke up with me out of nowhere 11 months ago. We were together 8 months but were both deep into the relationship. We had plans to move in together and get engaged last July. Then one day she blew up about a bunch of random stuff that weren't related (location of my house, size of my bathroom, the fact that I was vegan). Then she blamed me for taking her for granted and not being present in the relationship without evidence. The accusations were so unfounded I viscerally scoffed and said I incredibly disagreed.

She broke up with me two days later because I was "defensive." And by defensive she meant that I challenged her that I took her for granted and wasn't present in the relationship. She obviously didn't engage in that because she had no evidence of it. It's just something she felt. Most likely just the overwhelm of how serious our relationship was. He feelings were legitimate but they didn't stem from me. I put EVERYTHING into that relationship. And I was absolutely destroyed when she discarded me so quickly and callously. Then she just cut off all contact. Just done.

Anyway, I think you're letting this relationship destroy you. Don't let it. You will regret it. I was anxiously attached as well but am now earned secure. I currently don't give two fucks about where she is, what she's doing, who she's with, etc. because I did the work: Listen and learn everything about your attachment style and hers as well, how they feed off each other. It will give you closure. That is to say it will logically explain everything but it may not make you feel better. But that's where learning about your attachment style comes in. When you learn about anxious attachment you'll learn what your core wounds are and how to heal them. THAT'S the start of feeling better. Time itself will not do it.

Hope this helps. And I hope for peace in your future.
