<human>: Give me a shortened version of the text

Hi everybody. Tonight I plan on having a talk with my SO about our long-term sustainability as a couple, particularly my worries about it. I want to express that I've felt undesired, due to a lack of affection and expression from her (she is very stoic), and that I worry about how different we are. I've never dated anybody so different from me, and it's turned out more difficult than I thought it would be (barely any shared interests, parallel senses of humor, different wavelengths about how we experience the world).

I just need courage right now. I'm very bad at being up front and tactful when expressing negative emotions. Withholding my feelings has historically gotten me into worse trouble in the past, and I feel like I need to say some things.
<bot>: I want to express some negative feelings about our relationship tonight, but I'm scared. I'm just looking for some courage, in whatever form you've got.
