ABYG if may reservations ako with hangouts ng SO ko with a girl friend na sila lang?

Hi everyone, using a dump account lang. My (27M) boyfriend informed me (25F) that he was going out with a friend na girl. I used to be in a relationship na my ex went out with a lot of his female friends na sila lang without my knowledge. I’m aware na hindi naman talaga dapat pinapaalam lahat, but sana sinabihan man lang ako. And now my bf of 7 months, is doing exactly that, pero I still feel weird about the entire thing. Kasi we talked about it before and we both agreed na we both weren’t comfortable with hanging out with someone na opposite sex na kami lang.

Hindi ko pa nammeet si girl pero lagi niya rin kasing nababanggit sa stories niya na work-related.

Thank you po sa mga sasagot.
