I have no one to trust anymore besides my husband
Why do you only trust your husband?
I can trust him not to cheat on me anymore.
It makes sense to want people you can trust in your life. Maybe you can seek out new relationships and slowly work on building trust with others, so you have more than your husband.
I'm sure I'll be fine.
Although I'm happy you have someone you can trust, it's still important to have at least a few good friends you can have around as well.
