Need some help please, I really dont know what to do.. 
And sorry, a bit long...
I am mid 50's divorced 5 years.
Just over a year ago I met a man and we got on really well. After many weekends and some weeks together (not easy as we lived in 2 different countries although are the same nationality), I moved my life to be with him late last summer. I was a point in my life where I could and thought, why not. I had met his family and he mine and all seemed great.
Very soon I discovered he has a bad temper and with it a nasty mouth. And when he drinks - which is regularly - it becomes worse.
He is never violent, just verbally nasty.
He has extreme mood swings made worse by drugs he has to take for a medical condition which appeared also late last year, but then I find out he had this problem for a number of years.
Some days he is fine and all is normal and lovely, and others are me treading on egg shells as everything I do seems to irritate him.
I left for 5 days a couple of weeks ago when things got too bad, and he promised he would change. It lasted 3 days..
My ex narc husband was like this, although not the temper, and I seem to have found myself back in a relationship that I had to fight to get out of before.
Logistically the move home is possible but I moved all my furniture etc to live here.
Some days I just want to pack up my dog and clothes and drive away, others are not so bad.
It does not bother me at all to be single, I am not desperate to be in a relationship, and do not rely on him for any support.
But I just dont know what to do. And if I decide to leave how to do it.
What would you do? Am I just being a mug?
