I desperately want to leave my husband but I can't. Have you ever been in this kind of situation?
Oh so you want to leave him, I hope you are kidding with me. Why do you want to leave?
We had a huge fight before and he left me alone after the fight.
You should leave the relationship if you're no longer happy with the person you're with. Staying in a relationship that makes you unhappy will only make your life more difficult.
No, I need him. I'm too old to start over again.
You are never too old to leave anyone who is bad for you. Get some assistance and help for your situation.  You can't stay in a relationship just because you feel too old, that is just an excuse.
