Is this a red flag for a Libra man?

I met this Libra man on FB dating. We've been talking for about 5 days.

He mentioned his female best friend.

They used to be in a situationship but they're just friends now. He says she had feelings for him but doesn't want to be with her. She's not attractive.

They own a small business together and spend a lot of time together. He mentioned his ex girlfriend, that he dated for a month, tried to seperate them. It worked but he was very unhappy and it was against his will, to make her happy.

She spends a weird amount of time at his house. Lives with him but has her own place. They sleep in different bedrooms. She sleeps in his daughters room when she's over. They share a car, too. They have dinner often. She helps clean his house. Has a key and comes and goes as she please.

They talk and text everyday but told me he wanted her to be more independent. He promised me there's nothing more than friendship. She's not physically attractive.

Is this a red flag or a normal Libra thing?
