Trying to help an ESE who is in a relationship with another ESE:

Me: I just wish the two of you could have a level-headed conversation for once.
ESE: ...
Me: You need to sit down at a time when you're both calm and talk about your future and make a plan with a timeline and everything. Like, date for a year, plan marriage, get married. Or not.
ESE: We already made a plan but we don't follow it. We make plans in our "intimate moments". (said with air quotes)
Me: And then you fight. You two are always fighting or having intimate lovey-dovey talks, when are you ever just calm so you can talk about the relationship and get to know each other?
ESE: We are passionate people! She thinks I'm yelling when I'm not. Do I sound like I'm yelling?
(he kind of does, but I know that's how he talks when he's feeling strongly, which is almost always)
Me: No I know you're not yelling now but you were yelling on the phone with her.
ESE: We were both talking passionately!
Me: You've got to be able to talk some other kind of way if you want to get to know each other. Remember we talked about building relationships before you can commit to them?
ESE: ...
Me: What do you want to do?
ESE: I don't know! I don't want to break up with this girl, I love her!
Me:...
ESE: I've got to end it right now, cut it off!
(goes off and cries)
