Life will be better tomorrow. 3 years is just a short peroid of the whole journey. It is a kind of very painful as we all have experienced before. For example when you are 5 or 6 it is kind of very bad feeling for the lost of favorite toy. But now it is NOTHING.

People change, so does love. In Chinese tradition, a lot of people seem to believe that: you loved me, and as long as I did not do anything or betrayed you, you should then still love me and love forever. This is unfortunately not true. Love is not about right or wrong, it's about feeling. If I were you, I would not blame your husband for his love - if he really loves that girl. nor would I torture myself for a departing love. I agree with someone's reply - separate with your husband for a while, give both a bit time to calm down. see how things go and then decide what you want.

It's a heartbreaking feeling, I understanfd. Make more friends and talk to people about this will make you go through it easier. Best luck.

JJ：不要再哭了，哭是解决不了问题的。让自己平静下来仔细分析分析，或者计划一下自己未来的生活。

现在下决定倒不如见机行事，比起很多有缘无分的，两个人能够并肩走了不短的3年已经很不容易了。结婚后3年是第一道关，生物学也证明了刺激脑细胞的那种让人产生“爱”的感觉的激素最多只能维持这么长时间。老实说，他说的“他不爱你”很可能是真的，而你也迟早有一天发现你也“不爱”他了。
他给你留了“妻子”的位置，说明他还是念你们过去那么多年来积累的感情的。否则他会要求与你立即离婚，你说是吗？
婚姻不是靠所谓的“爱情”来持续的，相反，两人如果能建立更坚固更持久的比友情高一层的但又不像“爱”这么短绽脆弱的感情会更好一些。
不必流泪，你可能不久就会发现你自认为的“爱”很快就会过去，而真正留下的是什么样的感情。他可能只是被激素刺激，等新鲜感过后，他也会真正发现谁在他心里更重。

给你的意见：坚强些，冷酷些，放下困扰你的这种“爱”，客观地看看你们两的关系；打听你LG外面的那个是什么样什么背景的人，再考虑最后结果可能如何。要区分：
1 如果你LG只是暂时被迷惑
2 你LG本性沾花惹草
3 你LG和她死去活来，玩真的
