Is he lying?

Ok so I heard that the guy I been kinda seeing the past months has a girl that is interested in him or he is "doing" I heard this from my bro who heard it from another co worker (we all work together) the guy he heard it from isnt sure.. but he thinks that... him talkin to my bro in random convo cuz the guy who is friends with the guy I am seeing doesnt know anything bout me and him... so of course I get mad.. not even knowing if its true... he has told me several times that he isnt seeing anybody else but me... so of course I decide to question him bout it.. but I tell him I heard it from someone else not from anybody at the job, cuz I dont wanna get my bro or anybody else involved... so I tell him that I heard he has another gf, or he is doing someone else... he looked puzzled and was shocked that I guess had mentioned it... he said I must of heard wrong, that it wasnt him that person was talkin bout.. he said 'yeah im doing u" and I said "thats the problem, u aint been doin me, so maybe u r doin someone else" we havent spent time together in months... mainly my fault cuz of my busy schedule... so he after he leaves work he txts me and we discuss it further... but I then tell him he aint been doing me so he gotta be doin someone else... then he blows up! and tells me that I act like he gotta be ****in everyday, that I can believe what the hell I want that I am the last person he been with and he would tell me if he was doin someone else cuz he would tell me he wouldnt wanna deal with me anymore... idk what to believe now cuz usually when ppl get mad they are lying right? I mean we are not in a commited relationship but we have both told each other several times we aint seeing anybody else... Is he lying or telling the truth :/

it's hard to tell if he is lying or telling the truth..now your bro's friend says he is seeing someone and it may be true who knows...now keep in mind you are not in a committed relationship so at any time he may be with someone and I dont know if he will let you know to avoid problems. That't the thing about relationships that are not committed you cant or shouldnt expect the other person to just be with you cuz its more like an open relationship..theres no loyalty expected from either side.

Yeah I know... but we have told each other several times we aint seeing anybody else... and that if we was we would tell the other person.. which to me is kinda committed but just not fully... idk... I want to believe him just cuz of the kinda guy he is... and yeah the guy said he thinks the girl has a thing for him and he might be doing her but he isnt sure... all the men gossip round here... but just by the way he was acting idk if he got mad out of feeling guilty or the fact that i was accusing him of something he isnt doing.
