<human>: I am having a hard time with this and I can't ask my friends because I don't want them to hate him and they will not be objective.

My boyfriend made out with his friend while him and I were just talking (we met online) while we were close, we had not met yet. This did not come out until about 8 months into our relationship. I had asked him weeks prior if they ever had anything between them and he assured me that it was never like that. Later on he confessed that it had been like that. Later on still, after I asked, he admitted that it was while we were talking. 

While, yeah, it hurt to hear, I don't really care that it happened, I care that he was not upfront with me about it, and then outright lied to my face. The trickle truthing is a huge issue for me. I'm not worried that anything is going to happen between them now, she's become one of my best friends and I know neither of them would do that to me.

I've been very upfront about the fact that honesty is incredibly important to me. And he has come forth with a lot of things that he hadn't been honest about because he was embarrassed or ashamed or afraid that I would leave over. 

Today I found out that when she visited a few weeks after they made out and right after we had our first exclusivity talk, they slept in the same twin bed. There is a couch in the house, and I feel really disrespected that 1. This did not come out during our conversation about how he lied about her. 2. I feel it was disrespectful to our relationship to sleep in the same bed with someone he made out with. 

Is there any hope for this relationship? Are my feelings about honesty (that when it is something that concerns me, transparency is important, and that lying is never okay) too much to put on a relationship? Am I being unreasonable to be upset about this new information after we've gotten past the other lies? 

Please give me some insight, reddit.

Can you give me a shortened version of the text?
<bot>: Boyfriend hooked up with friend. Lied. Got over it. More came out. Got over it. More came out. Not over that.
