Have 你 ever been in 爱情 with someone so deeply that once your 心 was broken it was hard to turn back to the person 你 were?

Around this time last year, I had found out that my ex-boyfriend had played me for the four years that I've been with him. How did I find out?....through his fiancee on the internet.To make it even worse, he neglected to say that he was living with her then again what can 你 expect from a total jerk. The four years that I've been with this guy of course I thought he was Mr. Right, but never knew that the whole entire time he was breaking my heart. He 说 all those things that us girls 爱情 to hear. The thing that got me was he sounded do sincere about it that everytime he was say that he's 爱情 me, for example, I felt all warm inside. I've been broken hearted for almost a 年 and I will be for a long time coming. Since that has happened, I feel 更多 insecure about guys than I ever was before.
