How do you know she's the one?

It's really a personal question... if you and your woman are really good together and get along well then thats a good sign and if you wanna get married id wait like 2 years minimum before getting married. thats just me though. Good luck fella.

I don't think you look at someone and know they are "the one". You can look at them and see that they are all wrong though. Being "the one" is cultivated, as I see it. You decide that you wish to build a life with someone. Notice I said DECIDE. That means you are thinking it through without alot of romanticism going on, if you wish to be successful that is. Once you decide, then you set about creating the life you both wish to have. It isn't there with a look or an infatuation.

my husband was a known flirt/player. He didn't care who he hurt, etc. When he first met me he said he couldn't stop thinking about me. We didn't see each other for almost a year, then we started dating. I sat him down early on and told him I was not into games, and had too much drama in my life. If all he wanted was a cheap fling, he could look elsewhere. He always says that in that moment he knew he could never hurt me and wanted to spend the rest of his life protecting me & loving me. I knew he was the one for me when i saw how he treated me, and all the things he did for me. (emotionally) I believe you will "know" when a person is right for you. My husband "knew" and 12 years together and 11 married prove that we were both right.
