There are a lot of ‘ifs’ in order to get through the long, hard process of reconciliation, and it’s ok to change your mind at any point. It isn’t for everyone, it depends on many things, and love and time are actually NOT enough. No matter how much you love each other or how many years pass, if you never talk honestly and openly about it, don’t both commit to ongoing open, honest communication, or if he can’t see the need to support you with understanding and compassion as you heal, your chances are slim and resentment will eventually win out. Love alone isn’t enough.
So, if he has told the truth, is remorseful, genuinely wants reconciliation with you and puts you and your needs first, if he learns about affairs and why he did this (his issues, not yours, not the marriage. He is to blame here, not you. The state of the marriage is a separate issue, solely the cheater’s responsibility) then you stand a good chance of making it. If you are both willing to then move on to discuss any marriage issues which exist (there might be none, of course. Happy people can cheat too) and work them out (these issues are not what caused his cheating, btw, that was his choice in the face of other more honourable options) then even better.
But I won’t dress this up, you have to decide if it’s worth it, and it’s a huge emotional rollercoaster at best, for a long while. six months out is early days so don’t despair that you’ll never get through it, you need time to grieve the marriage you thought you had and the man you thought he was. He needs to acknowledge his brokenness and address it, with or without a counsellor, but if he thinks this happened because of anything or anyone else except himself, he has a lot of work to do. The blame and any associated shame are not yours to carry. Not one little bit. Take care, this hurts like hell, it’s a pain I’d never encountered before and it was physical as well as mental.
