What would you do?

What would you do if your ex boyfriend sent you a very detailed love letter from prison? A couple days I received this letter and it came across to me as very confusing. I had tried to tell him we need to give eachother some space because we need to teach eachother boundaries but this was the last thing I expected coming from him.

I’ll sum up the letter because it’s honestly so cringe to read. He went into detail about wanting to have sex describing everything that’s “gonna happen”. He said he loves me and that he will always be my man but also saying happy Valentine’s Day. Valentine’s Day is coming up but I haven’t showed him any interest in getting back with him. I’m more focused on getting things together first before hoping into a relationship back with him. I do like him still but I feel like we’re really just far from using the L word again. I’ll be honest the letter makes me super uncomfortable to read because he talks about me submitting to him and how he wants to see eachother the first day he gets out. I don’t have an issue with him but the fact he wrote all that out and told me what he wants to do to me just makes me feel weird. I don’t know what to do or how to respond. Thoughts?
