I'm not sure 4 months is that long....I've been with my T for going on 1.5 years and still struggle with the relationship. I think it's ok for you to hold off on the exposure therapy if you aren't ready yet. You can even try it and then take breaks along the way. I've had to pull back when it got to be too much talking about my past. It's frustrating, but I'm trying to accept it as ok. Slower is better, or so I've read.
