Split up with long term ex partner (his decision) nearly 18 months ago. We've had the odd text over that time, but nothing major. He's started messaging quite a bit this week, to the point where he's now just text and asked me to go over to his tonight (it was clear what he wants!). Had a quick FB browse and he's been in a relationship for the last 7 months.
It's grim. Do I let her know or just ignore and block him?
