Hi ljmom, welcome to Marriage Builders. The most glaring problem in your marriage is a lack of honesty and a long pattern of enabling. For example, it seems you have tolerated his affairs, rather than taking steps to end them. Sweeping the problems under the rug has been a huge mistake.
I would take another approach, starting with radical honesty. You need to tell your husband about your affair and tell him you know about his affair. You should both end contact with your affair partners immediately by sending them a no contact letter.
Please read starting here:
"The plan I recommend for recovery after an affair is very specific. That's because I've found that even small deviations from that plan are usually disastrous. But when it's followed, it always works. The plan has two parts that must be implemented sequentially. The first part of the plan is for the unfaithful spouse to completely separate from the lover and eliminate the conditions that made the affair possible. The second part is for the couple to create a romantic relationship, using my Basic Concepts as a guide."

From Surviving an Affair, pg 66-67
The extraordinary precautions do more than end marriage-threatening affairs; they help a couple form the kind of relationship they always wanted.
These recommendations may seem rigid, unnecessarily confining, and even paranoid to those who have not been the victim of infidelity. But people like Sue and Jon, who have suffered unimaginable pain as a result of an affair that spun out of control, can easily see their value. For the inconvenience of following my advice, Sue would have spared herself and Jon the very worst experience of their lives.
