<human>: Condense the text into a few key points

Let's call this girl Mary and my close friend Jack.
Me and Mary met like 2 years ago in class, just thought she was cute but didn't pursue her back then because of my low self-esteem. She and Jack got together 1,5 years ago, they are a lovely couple and fit extremely well. I've stayed friends with Mary since we had sort of similair interests and just were comfortable talking with each other.
I've known Jack for 6 years and we talk about all kinds of deep personal stuff like faith and views on marriage and such.

I respect their relationship and keep a rational distance between me and Mary, but I grew sort of a crush on her.

Note: I would never try and break up their relationship, hence the distance.

Lately I have been looking for a relationship myself and everytime I find a girl I could potentially like I compare her to Mary for some reason.

Like 'she's cute and shy but she doesn't have the right personality like Mary does' and it's annoying me and I want it to stop.
It seems to happen everytime I am thinking about a girl and I just can't turn it off. Ugh.

Is there anyway to make this stop whithout cutting Mary completely out?
<bot>: Close friend has a gf, I keep comparing other girls to the gf and it's preventing me from really hitting it off with other girls.
