Giving up on a long relationship

I’m thinking of ending my married life after 6 years of relationship and 1.2 years of marriage because I lack bond, companionship, and understanding, which drains my energy a lot. I’ve tried to make him understand multiple times with clear communication, but he still fails to acknowledge the issue or make an effort to fix the situation.

I love him a lot, but I don’t want to sacrifice my career and mental health. I don’t know how I’m going to face both families or handle the divorce phase, and I’m not sure how I’ll manage the situation and heartbreak.

Has anyone been in a similar situation? Any advice on whether this is a good decision or not would really help.
