<human>: I recently broke up with my SO(20F) and after a lot of much needed reflection, I'm finding that one of my biggest problems during our relationship was that I wasn't self reflective enough. When I'd have a problem I would tend to shut down and let it fester instead of trying to logically think of how to deal with it. 

Lately I've started journalling as a way of reflecting on my thoughts and feelings of the day. I feel like it has been easier than it would have while in the relationships because I don't feel worried about filtering my thoughts in any way. 

While I understand that openness and honesty are important in a relationship, I still think that not necessarily every thought one has must be communicated to their SO. For example, it would probably make her or I uncomfortable if we pointed out every person we saw that we thought was very attractive. While I never looked at other girls as potential romantic partners and I find my ex extremely attractive, I can't help but notice if I think someone is particularly attractive or not. 

I want to maintain journalling as a way to help me be more open with myself and others. But I think that if I was in a relationship and knew that my SO might eventually read what I'm writing, it would be hard not to think as I'm writing if my thoughts or phrasing might be upsetting to her. I normally have a difficult time being expressive with words, and I think that this filter, whether conscious or not, would stop my writing from being fully open, and make it much more difficult. At the same time, it just feels wrong to have something you don't want the other to see during a relationship.

Give me a shortened version of the text
<bot>: I think letting an SO read through my journal might put a filter on my thoughts and make it harder to be as expressive and open with myself. Do you think it is wrong to want to keep a private journal in a committed relationship?
