No to put you down but I was in your similar situation. Don't put too much trust into somebody just because you know them. Although most people have a few more years on me I have had every situation under the sun thrown my way. My soon to be ex-wife and I were good friends since we were about 14. After high school we went separate ways and 2 years later we hooked up. Got engaged 6 months later, she got pregnant 3 months after that and we got married last month. 3 weeks ago she has turned my life up side down, moved out, claimed she was a gay, never wanted married, only wanted the kid and so on. No to be sour but things can always happen. Thankfully I have a great family not only on my side but my in-laws as well. I still can say my wedding day was the happiest day of my life besides my daughter being born. Take some advice from a young old timer here. No matter how mad you may get from a bad day or whatever. Never go to bed without saying I love you. Communicate often, sometimes more than just words get a card and flowers just because. And always try to put yourself in her shoes. Best wishes.
