<human>: Am I making mountains out of mole hills?

In a bizarre non-relationship... we sleep in same bed but not a "couple". He's (M42) an alcoholic. I'm (F33) probably a co-dependent.  He shuts down and wants me to leave him alone when we fight. I want to talk about it and resolve things. We will have fights that turn into "why can't you just leave me alone" and I cant. I just can't leave it be. I feel like the fight is the end of the relationship and if we don't resolve it right now then he must hate me and I should probably just move out. Reality is, if he just gets some space it's usually ok after a while we can sit down and talk it out. I am interested in understanding my own behavior and getting past this fear that every fight is the end that every thing is over just cause he does not want to talk. Also any insight into why I may feel like the world is coming to an end at every request for space.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Am I making mountains out of mole hills. He wants space I think this must be the end. Its usually not the end... how do I let go and give him space? Is his need for space normal?
