Hi Bobby, yes there has been some damage done. However, M's can recover from betrayals of trust in really difficult areas like infidelity. I don't agree that there is really no way for you to develop her trust again.
It would help to know a little more about the circumstances of you sending these pics. Were they to another guy? A woman? What need in you did sending the pics fulfil - though you knew your S wasn't happy with them being sent?
Once you are D and with NC, things can feel unsalvageable - but M's do come back from that. Only time will tell whether yours is one of those or not. But your situation certainly isn't hopeless. Your W may come to have regrets about the D - who knows?
What are you doing to improve your skills around personal finances my friend?
