so basically, im 18 male, and i’ve been with my girlfriend for 4 months, not long but we had always been best friends so we gave it a go, of course we are really fond of each other but recently she has been chatting to other guys, i think its cause shes just a likeable person but i dont really agree with it, im scared that if i say something she think im being self centred and leave me? it would hurt especially more as we’d been friends for so long, i dont want to lose her cause i had some hard things to go through in my life and shes has always been the one there for me. i dont really talk to girls cause i dont want it to compromise us but she will just chat to any guy and take compliments easily, it s been starting to upset me cause i feel like i dont know who she really is, what be be the best way to bring this up? thanks
