It would be nice of her if she spent more time explaining how she feels and at least give you a sense of closure.
It is likely nothing you did, otherwise she would have probably told you. Was she married before? How old are you two?
It seems like neither of us can assume the reason she left, but your actions should be reasonable, no one can expect from you to read her mind.
If she wanted to talk to you, she probably would not block you from contacting her in every way.
This is a very fresh wound, cry it out for few days and talk to your friends. If you have mutual friends then you could maybe ask them if they know anything about what happened, if not, there is nothing you should do here as it seems clear she doesn't want you to bother her.
Either way, I am sorry man. I know it is very painful and that the pain will last for months, but you will get over it as long as you let it hurt and work on it.
Thank you for replying. She wasn't married before. I am 27 and she is 25. I think she just got cold feet. She called me yesterday and told me that she thinks its too soon to get married and she wants to see what else is out there. She also told me she loves me but she doesn't want a relationship with me. This is way too confusing for me. You are right, I am going to just focus on myself for a while and spend some time with my friends.
But ultimately, I want to win her back. I read an article on this and I wanted to get your opinion about this.
