So yesterday me and the boyfriend were having a converstion about him going to Montreal, Canada for a weekend or even for 9 days. I am going away to Florida for 9 days to visit my brother. I am going on a family trip and he is going on a guys weekend out to canada. So I asked him who he was going to canada with and he said I am going to take Melissa, Melissa is his female friend since high school. I was like alright thats fine, I dont care, he had a big smirk on his face when he said this. Then he said no I wont take her because I dunno want to put myself through the tempation of something happening because he knew there would be drinking involved and he knew something would have happened. Well he said something along those lines, I just dont remember what he said exactly. So basically he just came out and said that he would cheat on me. Then he said I am am only a guy or something along those lines.
Now knowing that from what he said, should I let him go on this trip or should I put my footdown and say NO?
