married for 4 months now but I have really regretted and I need your help.

I am 25years old. I have been married for 4 months now
but I have really regretted and I
need your help.
Before I married my husband, he used to bring all sought of cars to visit me in my
house and when I asked the job
he does, he told me that he is a
car dealer.
Just 3 months after our marriage,I got to know that he works at a car washing bay. So the cars he brought to show to me were cars that were left for them to wash at
the washing bay. How could he lie
to me like that?
How can I trust him in this marriage? The most painful part is that I am a graduate and I just got to know
that he is not a graduate.
Please help me because I am very
confused.
