<human>: Condense the text into a few key points

When we started out 1.5 years ago she told me that she had one boyfriend before me but that it was a LDR and they never did anything sexually. I on the other hand told her every person I had been with and how far I went with each person when we strarted off. I answered every question truthfully when she asked, and she had a lot of questions.  When I asked her she repeatedly said I was the first person she did anything even remotely sexual with, and I believed her. 

Two days ago she asked me for my Facebook password, which she has been after since the beginning, but I always said no and asked that she trust me without having to snoop. But two days ago, I gave in and let her have it. She didn't find anything except for an old conversation with my ex, which I didn't even know was there because I never bothered to delete anything. She was a little upset with the old message and deleted it. I said to her that the only people who suspect others without reason are those who themselves have something to hide.

So this morning she tells me that there was one time she visited her ex and gave him a blow job, and that's all that happened. I am okay with that because I had done things before her too. However the fact that she hid this from me and repeatedly told me that she hadn't been with anyone before kind of bothers me. We had already decided that we will marry each other, and now I feel like I don't know her. I trusted her completely and took her every word as the truth, and now I don't know if I can trust her fully again. I know this might not be that big of a deal to some of you but I cant help but feel lied to and I don't know what else she has lied about. Am I wrong to feel this way?
<bot>: She told me for 1.5 yrs that she she hadn't done anything sexual before me, now she tells me she gave her ex one BJ. I don't care about the BJ, I am unhappy she lied to me.
