Husband left me...feel hopeless

[jks]

I would say just send him a very simple text and leave it at that. I think he is showing you that he needs space. Give him the time he needs. Just like you said, "the ball is in his court." Do not pursue it and let him come to you when he's ready. It feels weird to pull away completely and to ignore big days like birthdays and such but it needs to happen. (I have to say that these type of days always made me sad but as time has gone on, it has gotten easier... I never thought I would say that.)
