guy friends?

I'm in my second year of college and I'm still making new friends. One of those friends is a guy and I can talk to him about my life like he's one of my girlfriends. I don't see my girlfriends on a daily basis because we have different schedules and instead of sitting alone or around campus by myself I'll sit and talk to my guy friend maybe like once or twice a week. Me and him first became acquaintances in my math class and one day my boyfriend decided to start talking or becoming "friends" with a girl he used to want to date and at the same time wanted to take a break... Coincidence? It really frustrated me so I started venting to my friend about it and that's how we started becoming really good friends. Fastfowarding to when me and my boyfriend met up I thought I couldn't trust him since I felt he liked this chick again even though he claimed he didn't but always wanted to hangout..long story somewhat short he dropped her after I wanted to officially break up and he gave me a lovey dovey apology. 
Now, he really doesn't feel comfortable that I have a guy friend because we snapchat even though it's all innocent. He's not someone I would date or whom I'm attracted to he's simply just a friend who gives me boy advice and advice my girlfriends and boyfriend can't give. I'd hate to sacrifice my friends for my boyfriend because it's hard for me to make friends period  and if we broke up I want someone to be there for me to talk to. as a person who lives at home and has never partied, college is so important to me; the friends I make now are the ones who are going to be there forever and I want the college experience. I assure my boyfriend all the time how much I love him and hes the one for me. I feel like I should be allowed to have friends including one guy friend. I don't have a problem with texting him instead of snapchat, that way my boyfriend could read them (which he would). Am I wrong?
