He basically told me he was content living at home taking care of me and still seeing her and that it hurt him so much to see me hurt and that the reason he came back home is b/c he felt it was the right thing to do. But pretty much he said he wants to date her and he sees a future with her.
In case you haven't heard of cake-eating, this is the prime example. He is content living at home with his W but also wants to date another woman. He gets everything he wants at the expense of of your feelings. Is that OK with you? I don't think so.
Since you can't get him to cut off contact with OW, you'll have to cut off his contact with you. That way he's only getting half his dream and will have to rely on OW to fill it (which she won't be able to do). This is the basis for Plan B. Send a Plan B Letter and make that the only contact you have with him. Have you read "Surviving an Affair"? Dr. Harley writes about how the WS is torn between the spouse and the AP and will ping-pong back and forth between the two.
You've done a good job by not answering his calls. What's the point in answering? What good does it do you? He just wants to try and convince you that it's OK for him to continue seeing OW. Or try to convince you he isn't seeing her anymore (like he already did). You've told him what he needs to know.
Only about 5 percent of affairs end up in marriage and 70 percent of those end in divorce, so those statistics should answer your question about whether WS and OP are going to be happy together. And if he was truly happy with OW even now, would he have called you 5 times since yesterday? Don't give him what he wants, which is to allow him to continue cake-eating.
