Questions: Marriage & Weddings

I posted last week about how I can't live with my husband's horribly trained dog any more. it's been 3 years and my husband has done nothing to improve the dog's behavior. I'm 7 months pregnant and I finally asked him to take the dog to live with his mother (an arrangement she has said she'd be fine with). he took the dog but ignored me all weekend and slammed a door in my face when I tried to talk to him. I am staying with a friend, but my husband has not contacted me at all. How long do I wait this out? He clearly resents me for making the dog go, but it had been three years of asking for change and seeing none, so I resent him too. I had a doctor's appointment this afternoon (which I always intended to go to alone,) but he hasn't even contacted me to ask how it went (everything is fine). I need to go home and grab more clothes but I'm not sure what to do now. Do i stay away and give him time? Do I move back into our home?
just a recap: the dog has knocked me over twice, he jumps, he claws, he snaps at your face, he begs, etc. and my husband rewards this behavior instead of correcting it. I'm "mean" and the bad guy for trying to train him. His dog came before me, but I don't want an untrained rambunctius dog around our baby. He's scratched me pretty badly and I don't want him to scratch the baby or knock him out of my arms or something. he also likes to snap at things below him (like if he's standing and you're lying on the ground, he will snap at your face). I tried to teach basic obenience for 3 years to no avail. it was all undone by my husband.

The seven-year itch is a psychological term which suggests that happiness in a relationship declines after around year seven of a marriage.

The seven-year itch can be analyzed quantitatively. Divorce rates show a trend in couples that, on average, divorce around seven years. Statistics show that there is a low risk of separation during the first months of marriage. After the ‘honeymoon’ months, divorce rates start to increase. Most married couples experience a gradual decline in the quality of their marriage; in recent years around the fourth year of marriage. Around the seventh year, tensions rise to a point that couples either divorce or adapt to their partner.

In samples taken from the National Centre for Health Statistics, there proves to be an average median duration of marriage across time. In 1922, the median duration of marriage was 6.6. In 1974, the median duration was 7.5. In 1990, the median duration was 7.2. While these can fluctuate from year to year, the averages stay relatively close to the seven year mark.
