Feel pretty inadequate compared to partner's colleague

[Ridiculeisnothingtobescaredof]

I am probably paranoid but i just feel like she has more going for her than I do.
She looks more attractive with a better figure (though I know that's entirely subjective)
I'm sure my partner thinks she's incredibly attractive.
She drives and I don't as i failed many times and gave up.
My partner likes very specific books and whilst we share 1 or 2 in common he told me that they have pretty much both read all of the same books, ones that I'd not even heard of.
She has a degree and a Masters, as do I but she got a first and I got a 2:2 (I'm being ridiculous now i know)
She works full time with my partner in a job that doesn't seem related to the studies at all but i found her on LinkedIn and she seems to do this very high flying job on a freelance basis
I'm proud of the work i do, it isn't fantastically paid, i mean I manage fine but they are relatively low paid roles even though I have the qualifications.
I help vulnerable children and adults for a living, I'm proud of it. But you could tell he was really interested and impressed by what she does when he told me. I'm sure she has more money than me too.
She's exactly his age whereas I'm 3 years older (probably meaningless but might help him feel more connected)
I'm also relatively quiet and introverted whereas she's more outgoing by the looks of it.

I know comparison is the thief of joy. However I just feel like nothing in comparison, i know i have things to be proud of but i just feel like she's a much better 'catch' overall.
I know people will say 'he has chosen to be with you', that is true but i don't think such things are always black and white, I think there are often nuances in between such as 'if you weren't together he'd like to be with her'.

How do I stop feeling like this?

Tbh if the biggest compliments he can think of to describe her is "she's neat and tidy" and "mature" it doesn't sound like he's wildly attracted to her. I mean it's not rip your pants stuff off is it?

It's not as if he's even says "oh colleague is so funny" or "colleagues haircut looks really good perhaps you could get highlights" or "colleague is so clever" let alone anything actually hinting he finds her attractive.

Although pps say he seems to know a lot about her it all sounds like really banal obvious and work appropriate stuff like what degree she got and her age - all things I would find it completely normal to know about colleagues. He doesn't even know if she's in a relationship! Surely that would be the first thing he would try and establish if he was at all interested in her.

Think you're really overthinking this tbh.

Its not the things you've listed you should be bothered about its the fact I am assuming he's told you all this and talks about her a lot for you to know so much?

Don;t show any jealousy or insecurity, whatever you do. As well as being incredibly ugly and unattractive, it will drive him into her orbit.

I'm not sure about this. I think that in a healthy relationship you should be able to talk to your partner about your insecurities, and occasionally show vulnerability without them finding it a massive turn off. We all need a bit of reassurance sometimes.

Yes if you can do it in a good way, sadly many people who do have these kind of issues use it to try to control a partner, not just for reassurance. The whole “I told you I was jealous and insecure so you can’t have lunch with her or him, you can’t be friends if you loved me you would respect my feelings and not see them”

Also if jealousy and insecurity is an issue you have it is your issue to resolve, it is not to be made wholly your partners problem, so asking for reassurance is one thing, but it needs to be coupled with what steps are you taking to sort your own problem out.
