He told me but 😠

So my significant other just came home from drinking. for context he messaged me while he was out and said that an older lady had a crush on him, didn't think much of it. He came home drunk and told me that the woman was rubbing his back for half the night (hand under the shirt)and he didn't know how to tell her no so he just let her. Then he tells me that she was asking him for kisses all night so he was kissing her on the cheek! He walked her home because she was drunk but one of his co-workers saw him and made a remark to him so they obviously looked like they were doing something. I don't think he would have told me all these details if he didn't get spotted on the way home... Also when he messaged he said it was an old lady, when he got back she was about 40
