Am I jealous or correct?

I don’t like to read long posts so I’m going to try to not make this long..

Basically my “Fiancée” is a really friendly guy. He helps everyone as much as he can no doubt and I don’t try to change that. When it comes to me though, he doesn’t show me that same face.

I’m already dealing with trust issues and one time he drove all the way to another state to drop someone who said they got kicked out to another location about 2am, but if I’d ask to drive me somewhere he’d have an issue. He also always try to flirt with this girl but she’s been dubbing it since she lives with her child

Father. He also sent her money a few times before, and partied with her.

His cousin gf comes over to sleep over because she has somewhere to go and her bf couldn’t take her (idk how that’s our problem)

Also out of state like two hours away but I told him I had somewhere to be that morning as well, my plans had to be canceled for someone else.. as usual. The whole ride he hasn’t even been conversating with me just talking to her

All the time which is fine or whatever.

But the way he talks would sound like

He’s flirting.

Then when we

Reach back in the house he mentions to her “don’t be a stranger” even she was confused like huh? What do u mean? Then he tried to play it off and say oh wen u and my

Cousin come down y’all should let me know. But what he really meant was he wanted her to keep in touch with him and communicate with him often. I Just felt really disrespected in my own house.

There’s more and levels to this but this is most recent and relevant.
