Do I have every reason to be upset at this guy friend/coworker?

So I guess you can say we are friends so called at work I mean we work together, but anyways I think I’ve been a little too nice to him which I realize he probably don’t deserve it tbh, he might be asking me if I have any snacks sometimes I shared an apple and other stuff with him occasionally, his asked me for candy and gum here and there and usually I always gave him in return, now overall he is nice to work with very friendly always greets me in the mornings chats etc but yea he likes to ask me for stuff like that consistently but not everyday type of thing, don’t know why but yea, anyways I haven’t noticed it before but I caught him few times just recently that his been doing little favors for this one chick we work with, not sure what the deal is with them but I witnessed myself one time she brought him a biscuit from the front on break ( I guess he didn’t want to walk there) than just days he brought her coffee twice I’ve witnessed as well, NOW it might sound like I’m jealous but has this boy ever done anything for me going out of his way? Like I've mentioned I’ve given him this and that when he asked etc and he be bringing that girl coffee? Now I think she might have asked him that one time but hellooo am I overthinking? Bc now I’m like maybe I should just end this so called friendship
