<human>: Summarize the given text in a few sentences.

I found out I have herpes yesterday. Test results are not in yet but it's pretty much a sure bet. I broke down in the doctors office thinking of all the future complications this would create for me. I immediately thought my boyfriend must have cheated on me but the doctor assured me that that wasn't necessarily the case. My boyfriend and I had plans to go away on vacation this week and my doctor convinced me that everything would be fine and to have a good time on the trip. After speaking to my boyfriend about my diagnosis he apologized over and over and promised he would be by my side every step of the way. He swore he never cheated and he must have gotten it from before our relationship. Tonight we got to our hotel and my curiosity got the best of me. I went through his phone and found texts and pictures to multiple girls through out our time together. I'm absolutely broken and being in a foreign country I feel so alone. I don't know what to do. The obvious answer is to try to survive the week together and break up when we get home but I can't help but think it would be easier to stay together considering my recent diagnosis. I can't imagine getting back out there and having to give a disclaimer to every sexual partner. This should be such a simple decision but I've never been more conflicted and betrayed in my life. Any advice or similar stories would be greatly appreciated. Thanks!
