I really need an advice...pls help?

Am a married woman but unfortunately not that happy. My husband is a macho type. How much I tell him that in a couple dialogue/communication is a must, he always run away telling me it will end up in a fight. (how cud he kw). Then I met a boy who we were in the same college as I was. I have love him secretly and he too but have never express our love to each other. It was now after 10 years that he confess it and I accept him. But as life is always against me, he got married this month under pressure. But he wants me to keep in touch with him. But being a woman I don't want to hurt another just for my own pleasure. But another part of myself want to continue.. What sud I do??? He is still on honeymoon and will be back soon... in two weeks
