I want to hire private detective to follow my husband – I’m certain he’s cheating on me

DEAR DEIDRE: IF I could afford it, I would get a private detective to follow my husband because I’m almost certain he’s cheating on me.

He is on his phone all the time and he never wants to have sex – unless I initiate it. My gut tells me he’s found another woman.

I’m 48 and he’s 50. We’ve been married for 18 years.

At first, he couldn’t get enough of me.

But for the past year or so, we haven’t had sex unless I suggest it. And often he says no.

It makes me feel unattractive and undesirable.
