Dear Miss Emily:

i don't know what to do. I've been on and off with my son's father for 3 yrs. now. He's back with his ex-wife. but he still sleeps with me from time-to-time. Now I found out his ex is pregnant.

-----------------------------Miss Emily's advice------------------------

Here's what you do: Run (don't walk) away from this creep. Set up reasonable visitation with the son you have with him, and child support (through the courts, if necessary). And last, but not least, look in the mirror and say, out loud: "From this day forward, you're no longer this man's dupe."  It's really that simple, unless you choose to be the fool he thinks you are. Your choice -- and it is a choice, you know.
