: My marriage has been on the rocks since 2008, when I caught my husband talking to other girls online. He swore he would never do it again and I trusted him, only for it to happen again and again. We have a 2- year-old and I'm pregnant with our second child.

He has now placed another ad online stating that he's a single dad. I am torn. He keeps telling me he loves me and wants only me, and he doesn't know what's wrong with him. He is bipolar and not taking meds for it. He promised this time he will get help and try to get better.

This is the fifth time he has placed an ad or chatted with other girls online. I don't know if I should call it quits or keep trying. I love him and want us to be a family, but I don't know how much more I can take.

- Torn in California

DEAR TORN: Because you still love your husband, make his taking his medication a condition of your continuing the marriage. He needs to be willing to prove to you that he wants you to stay.

If he won't do that, then you will have to decide if this is the way you want to spend the rest of your life. And please, for your sake and that of your kids, don't have more children with him until you're sure your marriage is on solid ground.
