Probably. I feel that by staying I would be condoning that type of behaviour and would be risking it happening again to myself or any kids that I had with them. If there were exceptional circumstances then I may consider not leaving, but off the top of my head I can't think of any good enough ones. There would also be really strict rules from that time on (e.g. counselling etc.). I think Oorkie made a good point that there are likely to be other ways they may be abusing you (e.g. by restricting your finances).
I hope this helps. Good luck with your situation.
