Without a doubt Dandy Lion, the LBSer can be TOO NICE! This is serious stuff. WE all have to be held accountable. I do not believe for one minute that we cause they to do this, just don't buy that. But as loveisntweakness says, it is a really good time to scrutinize our marriages and honestly evaluate and fortify some things, rebuild others, tweak this and leave that completely alone.
We need to look within ourselves and see what also needs to be changed. What needs to be tougher, more unconditional, more exciting, calmer, whatever... what would be better for ourselves to change. Should we be less DEPENDENT, more dependent, more loving, less loving, more demanding, less demanding... the list goes on and on. Bottom line, what would be best for ourselves and how would the MARRIAGE benefit from these changes.
Of course the spouse has to be evaluated as well. Get those rose coloured glasses off and be prepared to see him / her as he/she really is. What has to change if you are going to continue to have a relationship, marriage... friendship... or NOT!
We OWE it to ourselves after something like this, and even more so, when someone like yourself has already been through this 10 years ago... TO TRULY KNOW, what we want. AT this point DL, you have every right to not even want to be bothered with him. It would certainly be a consideration for me, but having let him have a totally free pass like you did, I think I might feel a second chance is allowed if both of you are in agreement.
For the record, on my Surviving Infidelity Forum/Chat room, there are a lot of people whose spouse had an affair 5 - 10 years ago and here they are again. There are some people whose spouses seem to have a fling every 5 years or so. To my mind, this is something completely different and one is dealing with a serial cheater, not sure you can ever really stop that. That is some sort of Thrill of the catch/adventure/forbidden fruit/excitement of the chase thing, not really MLC.
Start with yourself DL. You truly need to understand what would make you forgive so easily that you actually made it easier for him to live with his betrayal, disloyalty and disrespect to you. Glad you have a counselor and I would not stop until I had a good grip on what made me tick that way.
There are so many people who are terribly AFRAID of HOLDING THIS over their spouses head, forever. I don't buy that. I think you hold onto it until you can see that they really truly regret doing this. Trust is not something that SHOULD BE handed back ... EASILY! Trust is won, earned!
