At the risk of hearing "Every situation is different." I would like to ask a question about my situation. 

Is it too broken to fix.

My wife committed multiple affairs over a near 4 year time frame. It was a situation that was so extensive that it touches every part of a relationship (in other words, it isn't one AP or a slip up but full blown relationships and much more). I can't do anything related to intimacy without it being tainted or robbed of the meaning it once had. 

At some point is it just too much?

She is in recovery and doing the right things now (we are 19 months out). But I feel like I can't let her in. Every component of a relationship has been given away. I fear I can't "get over it."

Is there simply some damage too great to recover from?
