I've known friend, lets call her A for 5 years, we met through a shared hobby. In this time I've been to her house, and therefore met her husband. He seem (ed) like a really nice guy.
I've been single for a while and decided to join Tinder and try online dating out. I then came across A's husband's profile as a possible match. Not sure if he saw my profile. On his profile he says he's single.
A's husband got a tattoo about 6 months ago, I know this as she told me that she didn't like it very much. It's a big sleeve tattoo thing, before this he didn't have any tattoos.
The Tinder picture shows him with the tattoo, I only mention this as it means it probably isn't just an old account.
I know I need to tell her but I've already put it off a week as I feel too awkward mentioning it.
1- do i absolutely have to tell her
2- how the fuck do i start the conversation?
