I find the girl I’m seeing’s friend super cute!

I’ll preface this by saying I know this feels fucked up.
But basically I’ve been going on dates with this one girl for about a month. We met online. She’s not exactly my type but we really got along well and the more we’ve talked and went on dates the more I’ve started to actually like her. The thing is she has a super cute friend who is exactly my type and who is very compatible with me. Her friend recently got on the dating apps as well and I encouraged one of my friends to swipe on her because I know she’s cute and a good person. I just can’t help but be a little jealous tho because I know if I wasn’t going on dates with her friend i would’ve had a really good chance with her.

I have already make it clear in my mind that I could never. Since she’s the friend of the girl I’m talking to but it’s honestly kind of making want to distance myself.
It feels fucked up to find her friend so attractive and really like her personality.

Is this reason enough to stop seeing someone I’m really getting along with?
