This is a little complex. STBXH left our home in Dec to go sort his mental health. He went to stay at the parents house of a friend of his. No less than 3 weeks later him and the "friend" had a weekend away together sharing a hotel room and he has admitted in message to sharing a bed on multiple occasions but claims nothing happened. He moved home here for a week 3 weeks ago before leaving again and went to his mums. The following weekend he told me he was going back to London and is now there with her and her parents.
Can I divorce him for Adultery or am I better off going for unreasonable behaviour? There is a lot of financial stuff to sort but given we've been married 10 years this June and have 2 children I'm conscious that I may need to take different steps to ensure our girls future.
He's already wanting to take them to stay with him next weekend (2 weeks after our split) and introduce them to her and her parents.
