Help me please.

Ok so I met this boy in February when we met I asked him how old he was and he told me 21 but he’s actually 26 and I’m 17 and now I’m pregnant by him and he claims he has never did anything with me not only did he lie about his age he lied about his name so one day he left me in his car by myself and I looked in his middle console and seen a business card and went and searched the name on Facebook when I got home and it was him believe it or not so I told him I did some research on him and asked him why he lied about those things and he told me my research was wrong then he finally admitted that it was true about 3 days later when he came to see me. I should have known that was a red flag but I had feeling for him by that time so I didn’t stop messing around with him and now what makes it worse is I went and searched his name in Facebook again and seen he had 2 facebooks and I went in the one I never seen I knew about 1 but not the other and when I went on it I seen a women I thought it was his girlfriend it today I found out it wasn’t turns out he’s married to her and now I’m hurt and don’t know what to do all I can do is cry.
