Hi Lost1835,
When you know, you know. I’ve been there many times. My husband was even using diazepam to hide his cocaine use (badly I might add), as I still knew.
You can get test strips from amazon for about a fiver, dip it in the loo after he’s been, actually I even dipped one in the standing water in the shower after he’d been in it, its very sensitive. Thats if you’re too scared to ask him to do a test. At least with the information you can confront it without questioning your own judgement.
Hugs xx
