How long before some sexually transmitted disease comes home to you? No one deserves this, no one and this includes YOU! It's gonna be a long life with a man like this. Some people marry and find out after a couple kids and then feel obliged to work it out. But you are free. I know this relationship is familiar, but there are lots of nice people out there, have some faith, pray for guidance and look for happiness, anything would be happier than always wondering who he is with for the rest of your life. I had to do it and it hurt but I got over it and was carefull who I trusted with my heart the next time.
