User post: Is it okay for your boyfriend to spend the night at his friend's house?

So a little history first...my bf and I have been together for three years officially, sure we have had our ups and downs but we have stayed together this whole time and have a good relationship.I trust him with all my heart I really do, which brings me to my question. What do you think of my bf saying on next Friday he wanted to go to his friend (his bests friends) house to go out to a bar and whatever and that he would probably sleep there, as they would all be drinking. Now he also doesnt have a car by the way. Now I am 22 & he is 27, we have lived together for the past 2 years. Call me old fashioned but I just think there's no reason why he can't go out and have a good time and then come later that night. So should I tell him to go have a good time, or tell him I don't want him to go???


UPDATE: to all those responding thanks. I guess i should explain more...i DO NOT think he is going to cheat. this is not what this is about at all. First he is 27 and he has no car because we are fine with one. He works close to his job (in walking distance even), i do not support him. We split the rent 50/50 and he pays all other utilites/bills. I do trust him, and i trust the friend's house that hes going to ( which is a guy BTW). I wouldnt care even if they were going to a strip club even, but thats not really my bf's thing, so they (a group of guys) will head to a bar play pool/drink a little and head back to his friends house where he will be recording. My thing is i DO NOT MIND 100% him going, i do not care what time he comes in, only i do not think it is 'morally or eithically' right for two people in a comminted relationship to not come home to your partner to your bed. I feel I may be being selfish thinking this way but i dont think he will cheat at all(if he was going to i know if doesnt matter when or where).
