So you've been married 8 years, and he's been doing this I assume since the third year of marriage? You said you lost your trust in the 3rd year, yet mention more recent incidents. I can only assume he had an act of indiscretion in the third year, you caught him and now he keeps doing the same thing, 8 years later. This seems to be repetitive behavior, and you're right - you cannot trust him. Have you thought about separating?
