I mean I wondered right away if he took your drunk text that way but I didn't consider that much because to me your text seemed clear enough as you added you feel scared and you didn't say you want to dump him, just that you want to be alone right now is how I read it. (Even if I may not understand without further information as to why you'd want to be alone, I would understand that this is your feelings for some reason, whatever the reason may be) But to me it makes total sense that he didn't find it too clear and was emotionally overloaded by your text - I did mention this earlier - and so yeah it's believable to me that he read it that way. This would obviously be hurtful then to him.

He did act immature and rude afterwards though yeah, he was unable to communicate about how it affected him emotionally, and he's still punishing you with the blocking. It's clear to me that he's done that out of anger, having felt like you suddenly dumped him.

If it happened to him before, that someone randomly dumped or blocked him, then this sh*** behaviour would make a tiny bit more sense. Not an excuse at all!! If this is the first time he ever did it like that, and he can realise why it's problematic and take responsibility and not do it like this again, then it can be OK though. Him understanding more on what you originally meant will help with that if he's a decent person in any way at all.

So I mean, it can be understandable if it's a one off problem and not like a very long standing behaviour pattern for him that he doesn't want to work on (personality or character problem). I myself had a "good friend" who would randomly block me and ignore me and eventually I could no longer take it and I would get emotionally overloaded even if it was someone else doing the ignoring of me in some completely different situation. I'm still working on that one personally, so I can understand him (maybe), but he still needs to understand his own reaction and then take responsibility for his behaviour. Getting overloaded is one thing, how you deal with it is another thing.

It also makes total sense to me that he'd ask an - admittedly insensitive - question like that. This, "you thought dumping me would improve your eye sight situation?". I'm a woman but I got really out of touch with emotions for a while (long story), and so I can understand this kind of question trying to follow and understand the other person's sudden, abrupt emotional changes. But of course, since this was a text, it is impossible to tell for sure what the intention or the attitude is here on his end, no nonverbal information, tone, body language,... I suggest you two discuss this issue in person and *not* in texts. Trust me it would help a lot with not misunderstanding so much so easily.

So.... If you can talk to him in person and be patient with him when he's trying to understand what you meant originally, it can help him take responsibility. Let's hope it will work out that way and that he will make up for his behaviour towards you.

The blocking was a bad and punitive game but this question I don't see it as a game. Do note that I'm going by how you said in another post that he never behaved in bad ways before, for the about 1 year you two have been together. Like, I could be wrong and he could be playing games, but that's just not my immediate read on this.

What I'm thinking overall is, the stress affects things and the communication on both ends. So, all in all: Try to talk with him in person about this problem here, and in general try to not text about major stress or emotional issues either. Talk in person (or maybe over the phone) about such sensitive matters. If you get to feel very negative about something in life, stress, etc, try to not pour it out all on him in an impulsive way (regardless of being drunk or not, this has nothing to do with alcohol, and more to do with impulsiveness IMO. Alcohol will of course make you more uninhibited and impulsive too). It would be too abrupt and big negative emotions for him to deal with. Try to share about your worries in a more considered way. This is assuming he's willing to be attentive to you when you do share like that. Because that's his end of things, he needs to be attentive and supportive - in whatever way he can do that, don't expect him to be exactly like a female friend with the supportiveness - when you tell him about your feelings.

So, just my read on the situation. Hope it helps.
