My friend only tells good things about her life.

My friend and I have been together for 7 years but she tells me only good things about her job or relationship but later, either from other sources or from her I come to know how bad the things were. I will briefly describe the incident that was the deal-breaker for me

She told me that she got a high-paying job because of the referral, later I came to know that her relative was in a senior position at that company and helped her get the job and after 2 years she resigned because of some family conflict and her relative was constantly reminding her of the favors.

For these 2 years, I was happy for her but sad for me because I was stuck with a relatively low-paying mediocre job.

I want to continue my friendship with her but what should I keep in y mind going further.
