Abandonment and fidelity

My experience is not the same as most who post comments in that my spouse walked out on our marriage without there being another person he was involved with or interested in. However during our separation he was unfaithful twice with someone he ran into at a bar. We were back together about six years before I found out about his infidelity. I haven't found any information or anyone in a similar situation to help put together a process for restoration or healing. It's been two years since d-day and I feel alone and foolish for struggling still and yet there doesn't seem to be anywhere for me to find someone like me who can help with a plan or process....
