Long story short. Woman breaks up with husband and I meet her straight after the break up. Said she had been married but I didn't ask how long they had been apart. Dated for a few months became very close very quickly. Get dumped as she goes back to husband. Initially no contact then contact again. She's told her husband she wants to remain friends with me and we only dated. Been invited to a party at their house a post lockdown party when restrictions are lifted. Do I go or is it asking for trouble?
