I cheated on my boyfriend with a white guy..im 19 and pregnant! HELP!!?

ok so im 19 years old (black). and i cheated on my 21 year old boyfriend tyrone. and i feel really bad cause ive been cheating on him for a year and a half now after he tried to gain my trust back because he cheated on me last year 3x. so i did it all out of revenge. and not only did i cheat on him after he tried regaining my trust i cheated with a white guy (tanner) and i just found out 2days ago im pregnant and its a positive.i know the news will kill him, but i feel really bad to the point im suicidal. and plus tyrone hates tanner to an extent (long story)..and tanner is so freaking attractive it was hard to avoid him, he's tall, surfer built,nice, dark black curly hair and light green eyes. i feel soo bad ,all at the same time and plus ive never had sex with tyrone...so what do i do, he'll know the baby isnt his. how do i tell him?? it was all in revenge he hurt me and i wasnt trying to be a whore. and how do i tell my parents? my dads not the biggest fan of white guys, and you may say "oh he can't do anything your 19"..yeah but i still live with them So im still kinda under there control. was i wrong?? how do i tell them?? and who should i stay with cause to be honest i love them both...
