Help...

I’m in a relationship. We’ve been together for a year and he means so much to me. I truly love him. I’ve known this other guy for 7 years. We’ve talked off and on over the years but he lives 5 hours away and we’ve just never gotten the chance to meet up and hang out. Recently I’ve gotten the chance to go down and see him but he’s interested in me like romantically. I’ll always care for him but I’m in a loving relationship. Is it wrong of me to go down there to see him while I’m in a relationship knowing that he likes me? Like I said we’ve known eachother for sooo long and I just wanna meet the guy behind the phone screen but I have a bf and I don’t wanna lose him trust or anything. What should I do? 😩
