I'm so sorry for what you're going thru and agree with above that it sounds like he's just freaking out because of the baby, his age etc. Worst case, make sure you are as prepared as you can be for in the event he really doesn't come back..also, try not to be 'clingy' even if its your first reaction. He needs to see you're strong enough to do it without him (even if you don't feel that way...and fact is, sometimes if you act like it you'll start to feel it)...if this *is* a phase, it should bring him back to his senses faster than crying or begging him to come back.

I sure hope everything works out for you. I have similar situation with my man; he needs 'time to himself' but after the last time, I've had it. Now I need time to *myself* and he can spend every waking moment alone if he needs to. And yes this probably will bring him back....but at this point, I don't want or need him. I just hope it doesn't go that far with you and your hubby.

Good Luck!!
