Short story, rough time 5y LTR, she suddenly become super loving after seeing the orbiter one day and came home dressed up kinda Nice. She reassured me they had only talked..

We have made some future plans too but I strongly suspect that she cheated with him after reading about the sudden love behaviour.. She even started showing rings again...

I really want to give her the ultimatum today since it started to disturb me a lot now.

We are going to a restaurant tonight and we are going to have some wine too.

I Will till her: "After seeing him all dressed up you seem very loving to me even though we were supposed to take it chill. You Will tell me what you have done with him or i break up with you here and now "

Do you Think it its a good idea?

Before or after the restaurant visit? I strongly feel before but that Will probably ruin the night but idc honestly.
