I don't think him having mostly women as friends is a big deal because I mostly had men as friends 🤷🏾♀️ But there's an issue if he's not respecting the boundaries you communicated multiple times. He doesn't respect the relationship enough to care.
Have you tried asking him? Personally, I will not let anyone tell me who I can be friends with, especially if those friends predate the relationship. You may need to ask yourself why you feel threatened by his friendships and go from there. You can also ask yourself if you are okay with him telling you who you can and can't be friends with.
It means set your boundaries and if he crosses them then do what will work for you and your relationship
Could mean he just don’t care and lusting over other women but either way he’s disrespecting you a lot
