This guy flirts with me, but I think he may be gay?

He comes from an extremely catholic family in which homosexuality is not accepted. “Run away” from the place he grew up to go live in a big city abroad and never went back. Works in fashion, is very delicate, very attentive to his appearance, very elegant and with extreme good taste. Also very tidy. Likes art, fashion, aesthetics. All of his siblings and cousins are already married and with children since years. In his friends group there are plenty of single girls, including me. He flirts with all, with me slightly more than with the others, but never did anything with anyone. He’s also on tinder but is the sort of guy who unmatches people for nothing and I’m not even sure he went on a date with anyone. He says he’ll want children one day.
