Grew feelings for someone online

I have been in an online relationship that lasted around half a year. we ended up meeting but then later broke up. (this doesn’t have to do with the story, i’m just putting this in here to say i sort of take online things like these seriously) but anyways, after that happened, i started dating a new boy i had previously met in high school (we’re both out already) we’ve been together for 7 months and everything was really wonderful. I loved him very much but, i ended up making an online group chat with a few people who had similar interests as me. And I seemed to take a liking to one person out of them all. Me and him talk everyday, video chat, calls, we even play online games together. he’s also heavily interwoven into my online friend group. we’ve opened up to eachother a lot and i have developed feelings for him. I don’t know what to do since i think my newfound feelings made me lose feelings for my current boyfriend a bit. i know it’s wrong, but we’re not flirting or anything. i want to stop talking to the boy online since it would be better for my current relationship but i don’t want to just leave him like that either. but i can’t change my feelings on either side of the argument. i’m confused on what i should do. i don’t want to lose a good friend but i also want to keep my boyfriend’s feelings in consideration. being torn between what to do is taking a toll on me kind of.
