problem/goal: I (18F) have a partner (21M) na mahilig mag aya sa mga babae & most of the time wala siyang boundaries.

How do I deal with a bf na mahilig lumandi sa iba?

I don’t have a problem kung may girl na friends ang bf ko but whenever he talks to them sumosobra na. Like there was a time he hosted a pop up store event. So ofc he had to invite some of his friends. I got bored so I then checked his phone and saw his convo with this girl na “friend” niya. (mind you he used to be a fuckboy before we met kaya baka ex hookup or ex fling niya pala to) before he invited the girl dun sa event nilandi niya muna I would understand if “kamusta”-han ang messages but No, nilalandi niya. And yung girl pa mismo nag remind sakanyang may gf siya “Uy may gf ka na. Shooo shoo”. I confronted him already abt this and said na mag babago siya. Tapos recently may nakita nanaman ako sa phone niya na he has been doing this ever since the start of the relationship. It’s so uncomfy What to do???
