DH and I separated not three weeks ago. He’s still in our house, I’m trying to get him out and make arrangements for the children. He in the meantime has registered himself on tinder - I’m annoyed as I think it’s pretty disrespectful we’ve been married for 10 years, shall I say anything or just leave it? I found the registration email on his computer when I went to do a task on there earlier so he doesn’t know I know.
