''i slept with a 10 month pregnant lady....am i finished?

I would not like to reveal my full names but you can call me Mike. i am in deep sh*t, i still can't understand what made me do it and still question if i am sane. There is this lady called Julie and i met her in church, we first met at an evening fellowship....i was the coordinator for that week and after the sermon that day,she approached me, very pretty woman with a slender figure and nicely shaped buttocks. it was very visible she was pregnant cause her belly was protruded. She told me she was having nightmares and needed prayers...i prayed for her and after that i asked her about herself, she stated that her husband travelled abroad and has not contacted her for 4 months. i encouraged and talked to her and she became a regular at the fellowship. Then i made the mistake, She invited me over to her house for dinner which i harmlessly agreed,pls NOTE! i had no intention of sleeping with her. 

After eating, i was about to leave, she told me to stay a little longer, we sat on the couch and talked, she asked me about my personal life and i told her i was single...she started acting funny,commending my looks and stroking my hair...i felt and upsurge in my pants, i tried controlling myself but i just couldn't, she then kissed me and we did it. since then i have not been myself....i feel i am cursed....pls can you help me?
