Ask him why he does that and tell him your uncomfortable with it

Don’t let your boyfriend mess you about @oswinoswald75, he really shouldn’t be flirting with other girls, he should put you first and love you unconditionally Jess, you deserve so much better, if he keeps on doing that, I honestly would move on and find someone who will treat you right, try to talk to him about it, it’s up to him to listen and change, I’m always here if you need to talk Jess, feel free to message me anytime if you want, my inbox is always open, stay strong, you are never alone (hugs)
