Anyone else stuck in loser mode

I’m(30M) stuck working at a company for 8 years in a dead end position with no opportunities for career advancement. But I don’t mind that because I’m in a stable position as I’m able to do my job perfectly, great benefits, I’m able to pay my bills with no problem and can go to vacations with my wife 1-2 times a year even though the pay is low. Over the past few years I’ve gotten 3 job offers which all had a great career path but I declined all of them because I don’t want to leave this company and risk losing the stability that I have now. I also don’t like going through change. I’m happy here so why should I have to change that. What if I keep doing this to myself for 40 years. I’ll be stuck at the same position, same company from college to retirement? This puts me in loser category right?
