Boyfriends parents judging me?

Me and my partner have been together for over a year now. I am coming to the end of my degree.

Since I’ve been with my partner I’ve had 5 part time jobs (0 hour contracts). I have since handed my notice in at my current job as I am starting full time employment in May. My partner told his mum and she seemed to get weird about it. Saying how I’m always in different jobs and never seem to hold any down.

I feel really offended by this, as previously I’ve held down jobs for a good few years, and feel it’s unfair. I told my partner and he said she’s only seen what’s happened in this time not in the past, which I understand. I just feel really judged and looked down on.
