Will he ever regret leaving me?

[Tine]

I don't understand. Everything was great. We rarely argued. We had lifelong plans. He talked marriage and kids. And then he ripped everything away within a snap! (I didn't see it coming AT ALL) How can he say these things to me and leave me hanging, "I want you to be the mother of my children.", "I want you in my life.", "I want you to be my wife." yada yada yada. I don't get it. He led me on and made me think this was it. How is this even possible? Are men really like that? Will he regret leaving? I was really good to him! I swear! Oh, btw, he even blocked me on Facebook. I am not upset about him leaving, I am upset about how he wasted my time pretending to be nice to me!
