Re: Affairs (Physical and emotional)
"The 5 Love Languages" is a good book. I highly suggest it...I'm not advocating staying in a relationship like this but it does help you think about ways you can reach him emotionally. "After the Affair" is a good book to read if he comes around and wants to work things out.
Ultimately, do what you can but he's not willing to give it a good effort then you need to prepare yourself. Find a job, speak with a lawyer or counselor, put away money. Do you have family who can help you get on your feet? Prepare for the worse, hope for the best is all I can say...
I've BTDT, mama...my husband decided to pull his head out of his butt and it's been a long road of healing for both us, but we've learned a lot and hopefully we never ever have to endure this kind of pain again.
