Alright so I've been dating this guy for about I month (I know not long) but we've know each other since we were 5 and decided to give it a go since we both have always liked eachother, We grew up together in Michigan but he moved to Ohio, He came and visited me last week and it was great we kissed and all, I couldn't be happier. BUT today since random chick DMs me on instagram sending me a screenshot of my boyfriend commenting 👌👌on her instagram photo, now I'm not really mad because my boyfriend always tries to encourage girls confidence levels and he's a sweet guy so he comments nice things except on mine they're a little more...intense 😏...but now this chick is saying he's flirting with her which I know is a lie, but my boyfriend is getting an attitude at me cause I told her to back off and that she's just asking for attention..he went camping and left me on my period 😔and I just don't want him commenting on any girls things cause it makes me a tad jealous and girls take it as flirting...what do I do? I asked him if he'd be okay with me doing it and he said no... so I asked him to only say things he wouldn't mind guys saying to me or things I would say to guys and he promised not to do it anymore...Am I wrong to get jealous for him doing this? And shouldn't I want him to quit? He says it's nothing..
