Simple answer is: give him space. He clearly has a lot on his mind, and being sued is a big deal. Especially if this just happened, that last thing on his mind is relaxing and doing anything together. Don't take it personally, it's not you. It's honestly just him needing to take space to deal with the severity of the situation.
The more pressure you put on him or bug him about simple things, the more he will push you away. He needs support. Don't bug him about his haircut. He's already feeling low about an accident being his fault. He needs you to put no demands on his time, certainly don't nag him, and don't say anything negative to him. The last thing he wants to deal with is a fight or drama with you. The less drama and stress you have, the more he will want to be around you during his time of stress. He needs a relaxing, supportive way to deal with this. Not additional problems to deal with.
You may try sending him a SHORT apology note and let him know you're sorry for what he's going through and you're there for support if he needs. That's it. Don't text anymore than that or it's likely to blow up in your face and the results will not be favorable.
Just give him a day or two and he will text you back, I'm positive. Just let him have the space he needs. Don't text him or call him, let him come to you. Don't be alarmed if it takes a couple days. The question is, are you secure enough to give him the space he needs to deal with this?
