don't know what to do??

Jo
So my intuition is very strong..a few weeks ago I kept having a feeling that my bf was lying to me, I brought it up multiple times that I felt like he was keeping something from me and he knew how much I hated being the gf in the dark. I then found out myself  that my bf was lying to me about smoking and having more people over at his place than what he originally told me. 
I still have not forgave him completely bc lying is a big thing for me. I'm not mad about him doing it even though I find smoking nasty I'm more angry about the lying..so I gave him an ultimatum. If he ever lies again we are done. (We have been together for almost a yr and a half) recently I found messages on his phone with a group message of guys that he wanted to "H clap" this girl and that if he "didn't make out with this girl by the end of the night that he would be a failure"  and how much he liked her boobs and ass. this girl is someone he has been friends with for years and has came up to his place multiple times but is supposedly talking to one of his friends that also hangs around. He says it's just guy talk and that he was drunk but I am very hurt by this and don't know if there is enough trust built back for me to believe him about this "guy talk". I told him that they were very disrespectful towards me and I will not accept it...I just don't know what to do or what to think...
