I'm sorry you find yourself in this position
I'm glad you are seeing a therapist, that will really help you get back on your feet. You may also, at some point, and not necessarily right away consider looking into a marriage counselor.

I wouldn't put that restriction on yourself to not bring it up now in the new year. There will come a time when you will comfortably not want or need to bring it up but let yourself get there on your own path. Anything less will rugsweep the issue and cause more damage and lead to resentment. One of the biggest things I've learned (ok, I'm working on learning it) that if there's a problem you have to deal with it.

The only timeline that will work here is yours and if your wife is deserving of your marriage she will be willing to work with it. At a year past the event I still sometimes bring it up. Now it's usually needing a quick reassurance rather than a long drawn out discussion on the what's and the who's but this can be incredibly damaging to one's self esteem.

2 months...it's a long road. I remember the times when he was at work....or not within eye sight even. It was crazy-making. Can you ask your wife to send you a texts throughout the day? One when she gets to work, breaks, leaving work. Texts letting you know what she's doing. It seems ridiculous but that did help earn some trust.
