matthew is your husband, you are his second wife, his wife doesn't know you are married to him, you were in bed with him making out, she entered and saw you both, you both jumped off each other and acted like nothing, but it was obvious since he was naked and you were naked too, he said to his wife "I can explain!!" she shushed him and said "I don't care." She left the both of you, he didn't care about her but he was pretending he cares so she won't hate him more, he continued kissing you
