Need some advice..

My boyfriend and I have been together for about 5 months almost 6 hes 23 and I’m almost 21.. we both work together that’s how we met in the first place we became best friends instantly. And we’re best friends for about a year and a half and then finally got together.

Before being together he use to get around quiet a lot and was known for that. Until he started dating me he’s cut off every girl from the past ( on his own terms I never made him). And he’s so loyal and faithful and treats me like a queen. He’s honestly the best thing I’ve could’ve asked for. I was in a 3 1/2 year toxic relationship before him so this is refreshing and I’ve never been happier.

But recently a lot of the girls at our work have been starting to hit on him ALOT and make comments saying they are going to try and break us up and that they make him happier. Some of these girls are 10 years older then me and 8yrs older then him. I usually do not let it get to me because I know at the end of the day he would never cheat and I’m the one dating him and not them. But these last few days it hasn’t been sitting right in my stomach.

Everytime I see a girl flirting with him I wanna cry. They come into the store on their off days wearing very little clothing and flaunting. He never notices because he does work so hard, but I always ask and he’s so shocked when it happens... I wanna say something to them because everyone at our work knows we’re dating.

It’s starting to come between our relationship and make FaceTimes and calls very short now, because i can’t stop thinking about the girls and if does want them of if he’ll go back his old ways before we were official... he feels so guilty because he wants nothing to do with these girls, and I believe him 1000% it’s just me who hates it..

I guess the point I’m trying to make is..

and I being over exaggerating and just making this bigger then it should, or should I be worried and confront the girls??? I’m so confused and it’s finallt starting to take a toll on me..

( please be nice too.. I know this is probably confusing or has a very simple answer.. )
