Did I lose my soulmate?

It was a match made in heaven. Both of us genuinely love each other, more importantly we understood each other and communicated rather well. I feel like I caused her to bottle up her feelings with some criticism.

The subject of the criticism is intimate so I won't reveal any more about it other than that. She did not take my criticism well and she tried to avoid the topic in anyway. My mistake is that I insisted on talking about it until she was totally frustrated. A few days later she let me know that she'd like to breakup because she felt as though my criticism is an attempt to change her, also she felt the need to say that she's is walking on eggshells even though I was and always have been open to her input and opinion. I feel like there were other factors that caused her to bottle up her feelings, but I'm not entirely sure if I'm right.

The convo got a bit ugly on her side and at one point she said she would never come back to me even "if I gave her gold". I wonder if she says this because she is enraged or actually means it.

I wonder if I'll ever see her again as she no longer texts nor answers me. I feel like we are made for each other. She makes me a better person and I love her for who she is. Maybe I was wrong to criticize her about something so sensitive and even worse insist. It's in my nature to make amateur mistakes as I don't have much relationship experience. I can't help but feel that I may have lost a very special girl and relationship.

Before this we had one major argument. Other than that it's been 10 months of connection, joy, memories, appreciation and support for one another.

It takes a lot to describe a situation like this, and even with everything I wrote I feel like I couldn't express the whole picture. I hope however that this provides enough context for everyone to express an opinion that accounts for both her and me.
