My boyfriend is like a love sick puppy one minute and then cruel the next

DEAR DEIDRE: I used to be fun-loving and the life and soul of the party but my partner has sucked every ounce of self-esteem out of me.

I’m 36 with two kids and I’m cross with myself for going back to my ex.

I hate who I’ve become since I’ve been with him. He shouts and berates me in front of others.

He calls me names and if I confide in him, telling him a secret, he threatens to blow my private thoughts into the public domain.

He’s a police officer and he’s been married twice.
