TLDR: My partner is needing to figure his own "stuff" out, we are needing to take a break/breakup and I am looking for a firm, kind, and encouraging script.

Hi! My boyfriend and I have been together for a little over two years. In August, I (28) had a miscarriage that ended up being more traumatic than I would have anticipated, my boyfriend (30) wasn't as supportive as I would have hoped (he was kind but didn't know how to help/give comfort), but I also contributed to this by being extremely withdrawn and reactive (also my hormones were going crazy.) We were already trying to navigate the next steps in our relationship and the miscarriage and our reactions made that harder to navigate. He is very private and I believe the miscarriage and people knowing more about our personal lives brought up a lot of difficult feelings of guilt/shame/inadequacy(?). Since then we have both taken a step back and are trying to figure out where to go from here. In our conversations he has expressed sadness about the loss and has also told me that this relationship has shown him things about himself/relationships that he is now trying to figure out. Sometimes I think he resents me for being the person to "show him" these things, simply because he has never been this close to someone before. He also has a massive amount of anxiety about student loans, money, and if he has enough saved (he has a good job and is financially stable & this is not something I am worried about.) He seems very lost right now and says that him moving forwards without addressing these things on his own won't lead to the best outcome for us, but he knows that might come at the cost of losing me. I have read so much in this sub but I am looking for some sort of script that acknowledges that I can't wait around and need to step away but is also encouraging and motivating? I have never doubted his care and love for me, I have always known he would be an excellent father and it is something we discussed a lot, which makes this situation painful. But I am also okay on my own and I want him to become who he needs to be and self-assured. Any advice is very welcome.
