Just read your update. :(
He absolutely IS abusive. He WILL only get worse.
The marriage thing? Enough on it's own to know that this man is DEEPLY flawed.
He will hurt you in all ways imaginable.
Get out, get out, get out.
Please? Or you will kick yourself when you survey the devastation that is your life in 5, 10, 15 years time.

2 women a week are killed by their partners.
A man that is cruel to a pet, will go on to get physical.
Put ALL your feelings to one side and take the decision you must take.
You have a supportive mum, plenty of women in your position don't, so grab the opportunity with both hands and get out of this.
