For me, I believe that's exactly why I married my H. He was so sweet, caring, loving, all the things that I longed for. Did he have his flaws, yes, did I have mine, yes, but we, like you said, we overlooked them because we wanted to see the best in each other. I had concerns before I married him because he seemed almost too good to be true. Well, my intuition was right, he was. And now, I don't know if I'll ever "get over it" because now I see all of his flaws and now I have to deal with them and now - I don't like his flaws. Again, I'm not throwing in the towel, but I don't believe everything he tells me. For example, I've always been very particular in paying bills, never late, etc. He is constantly late on bills to a point where I get phone calls regarding unpaid amounts, I've even had one of our services disconnected for unpaid bills. Of course, he lied about it and said "I paid them" but as soon as I asked a few questions, it was obvious to him that I was quite aware that he was lying. I didn't embarrass him or call him out on his lie, but he knew that I knew. It annoys the crap out of me. I could go on about pre marriage and post marriage, but I hope this post gives you some idea of what he's like.
Thanks for listening and thanks for your posts. I really relate to what you say.
