What should I do, I’m catching feelings for him?

There’s a guy I’ve been talking to as friends for a little over a month. He said he has a girlfriend but I actually found out that he actually has a fiancé..

We never flirted with eachother we just talked and I asked him about his nationality because he’s from another country and he speaks French...

we have a lot in common so there was a lot to talk about and I would tell him about my guy problems..

so oneday... I asked him about his wedding and I asked him if he had any friends that I could date...

he said yeah but he also said that he would be jealous..

I asked why.. and he said “coz I love u”

he said he feels a deep connection and a strong vibration between us..

I feel the same way but I don't know if he’s for real or I don't know what to do
