Infidelity Support Group
Any relationship in which one partner engages willfully in sexual relations with another outside of the partnership is considered to have experienced infidelity. This breach of trust is often traumatizing for the faithful partner as well as the relationship, and support is often needed to heal emotionally and to decide whether or not the relationship should continue after...
Ask what you need to but you may not always like the answers you get. They will be hard to hear sometimes!! good luck!!
But it is good that he seems willing to answer them. What I would do is write out your questions on paper. Cut them up into individual pieces of paper, one per question. Stick them in a jar and place them somewhere where he'll see them. Then when he is ready, he can chose which ones to answer. That will give him a chance to read the question, think about it, and formulate a coherent answer that hopefully will be more than just off the top of his head. And give him a chance to attempt to remember details.
But, think hard about what you really need to know. If the answer to a question is needed to help you move on, then ask. If it is only curiosity but probably wouldn't do much to help you get closure, may even give you images that will haunt you, then you may want to not ask those. You're call. But remember, once you've been told info, you can't unhear it, or unknow it. If you have him describe a typical sexual encounter with the woman, for instance, you'll always have those images in your mind and can make things harder for you, not easier. So consider each question carefully as to whether you really need to know it.
I found out about one affair about a year ago and then the last affair about six months ago. The questions just recently stopped within the last couple months.
